Larimore; Adaptics, Inc, Dale E. Seborg; University of California, Santa Barbara Date: Friday, November 21, 1997 (during AIChE Annual Meeting week) 8:30 AM - 5:30 PM Location: Sheraton Grand Hotel, Los Angeles (The latest information is available on the Web at http://www.adaptics.com) SYNOPSIS Traditional process monitoring in industrial plants is based on comparing measurements to specified limits, and on the experience of the plant personnel. More recently, statistical quality control techniques (SQC) methods have been widely used for product quality control. However, the standard SQC methods are based on the assumptions that the process dynamics are negligible and that the process disturbances are uncorrelated. But these restrictions are not valid for many real-time monitoring problems where the process dynamics are important and correlated disturbances are the rule, rather than the exception. Thus, more advanced monitoring methods are required for these applications. The potential payoff is the early detection of small changes in the process that can be corrected or compensated to reduce their ultimate impact on process performance. In this short course, the traditional methods of process monitoring and statistical quality control will be reviewed, and several advanced methods for handling process dynamics and autocorrelated errors will be critically evaluated. These advanced methods include principal component analysis (PCA), projection to latent structures (PLS), and canonical variate analysis (CVA). They are based on mutlivariate statistics, time series analysis, and system identification. Numerous simulation and experimental examples are presented to illustrate key issues and to provide comparisons. A new automated method is presented for identifying the system dynamics and autocorrelated error structure based on canonical variate analysis (CVA), a generalization of the PCA and PLS methods. The CVA approach allows for the completely automatic modeling of the process dynamics and error structure. From a software user's viewpoint, the modeling of the process dynamics and errors is no more difficult than fitting a static multivariate regression model. The CVA method is statistically optimal even in the presence of known or unknown feedback paths that are often present in process applications. The CVA method is applied to a number of process monitoring problems using both simulated and industrial data, and is compared with alternative monitoring methods. COURSE OUTLINE 1.

Candidates must have or be about to complete a first class or upper-second class honours degree, or equivalent, in a relevant branch of Engineering or Mathematics. The candidate must be a U.K. or European Community national. The student will receive up to #8,000 per annum, and, in addition, all University fees will be paid. The student may be asked to assist in a limited amount of teaching or demonstrating. Project: Sliding Mode Control, Fault Diagnosis and Isolation Supervisors: C. Edwards & S.K. Spurgeon In the formulation of any control problem there will typically be discrepancies between the actual plant and the mathematical model developed for controller design. This mismatch may be due to un-modelled dynamics, variation in system parameters or the approximation of complex plant behaviour by a straightforward model. The engineer must ensure that the resulting controller has the ability to produce the required performance levels in practice despite such plant/model mismatches. This has led to an intense interest in the development of so-called robust control methods which seek to solve this problem. One particular approach to robust control controller design is the so-called sliding mode control methodology. This approach is characterised by a control structure which is switched according to some predefined logic to induce a so-called sliding mode behaviour. This is an on-going area of research within the Control Systems Research Group. Recent theoretical advances have been implemented successfully on automotive applications, process industry furnaces and helicopter simulators. Work is currently in progress to extend these results and to develop effective design algorithms to exploit all the available degrees of freedom. Of special interest is the use of sliding modes for robust control, fault diagnosis and isolation.

It consists of 9 permanent scientific staff members, 6 permanent technical support staff, 4 postdocs and 15 PhD students. Its main research topics is the development of system identification and control algorithms for linear and non-linear multivariable systems in different application areas. Three different areas where the group is actively participating in sponsored research projects are: (1) The mechatronic and robotic manipulator industry. (2) The area of computational intelligence characterized by the use of neural networks and fuzzy logic for e.g. solving multi-criteria decision problems. In this area the group is participating in different EC projects FAMIMO (a basic research project LTR 21911 standing for ``Fuzzy Algorithms for the Control and Multi-Input, Multi-Output processes,''), FALCON (the ESPRITIII Basic Research Working Group 6017) and ERUDIT (``European Network of Excellence in Uncertainty Techniques Development for Use in Information Technology''). (3) The modeling and control of nonlinear systems in the process industry, where the group is participating in the 4 year research project IPC-NL (``Identification and Predictive Control of Nonlinear Systems in the process Industry,'') sponsored by the Dutch National Science Foundation STW under contract DEL55.3891 and involving 2 Ph.D. students and 1 Postdoc. The group has different vacancies for postdocs and Ph.D. students. First, in an EC sponsored Brite-Euram project, there is a vacancy for a post-doc fellow for a period of 3 years and for a research engineer for a period of 12 months. The scope of the project SCOOP is the optimization of the seat comfort in automobiles. The role of the SCE group is the development and implementation of a model based controller for a nonlinear mechanical actuator. Apart from interest in fundamental aspects in the development and design of algorithms to solve the identification and controller design problems, the close cooperation with the industrial partners in the project (such as BMW, IVECO, British Leyland and Renault) require openess towards industrial applications. Second, in an innovative research project sponsored by the TU Delft, there is an opening for a Ph.D. student for a period of 4 years. The scope of the project is the development of a fault tolerant controller that can cope with failures in the sensors, actuators and dramatic environmental changes. The application, including an up-to-data cv and three letters of recommendations should be send to Dr. M. Verhaegen.

HARD. ISBN 3-540-76144-6. L32.50 A volume in the series: "Advances in Industrial Control" There is some degree of separation between the development of advanced control algorithms within the research community and their use in industrial practice. Several strategies developed from power plants are here examined in the context of their industrial application. The techniques described and applied are: - Modelling and Simulation - Adaptive Control - Model-based Predictive Control - Frequency Domain Control and Robust Optimal Control - Fuzzy Logic Control Their effectiveness in this control process is assessed and the various techniques' advantages and drawbacks are analyzed and compared. The results obtained can be readily extended to other industrial processes; in this context, the solar control process examined provides an ideal test-bed since it exhibits many of the problems found in other processes, such as nonlinearities, changing dynamics and strong external disturbances. This is a comprehensive analysis of the practical application of different control strategies that will be of interest to control engineers working in solar power systems and throughout other process industries, and to researchers, scientists and graduate students in this field.

Demmel Designed for use by first-year graduate students from a variety of engineering and scientific disciplines, this comprehensive textbook covers the solution of linear systems, least squares problems, eigenvalue problems, and the singular value decomposition. The author, who helped design the widely-used LAPACK and ScaLAPACK linear algebra libraries, draws on this experience to present state-of-the-art techniques for these problems, including recommendations of which algorithms to use in a variety of practical situations.If you are looking for a textbook that - teaches state-of-the-art techniques for solving linear algebra problems, - covers the most important methods for dense and sparse problems, - presents both the mathematical background and good software techniques, - is self-contained, assuming only a good undergraduate background in linear algebra,then this is the book for you. Algorithms are derived in a mathematically illuminating way, including condition numbers and error bounds. Direct and iterative algorithms, suitable for dense and sparse matrices, are discussed. Algorithm design for modern computer architectures, where moving data is often more expensive than arithmetic operations, is discussed in detail, using LAPACK as an illustration. There are many numerical examples throughout the text and in the problems at the ends of chapters, most of which are written in Matlab and are freely available on the Web. Material either not available elsewhere, or presented quite differently in other textbooks, includes - a discussion of the impact of modern cache-based computer memories on algorithm design; - frequent recommendations and pointers in the text to the best software currently available, including a detailed performance comparison of state-of-the-art software for eigenvalue and least squares problems, and a description of sparse direct solvers for serial and parallel machines; - a discussion of iterative methods ranging from Jacobi's method to multigrid and domain decomposition, with performance comparisons on a model problem; - a great deal of Matlab-based software, available on the Web, which either implements algorithms presented in the book, produces the figures in the book, or is used in homework problems; - numerical examples drawn from fields ranging from mechanical vibrations to computational geometry; - high-accuracy algorithms for solving linear systems and eigenvalue problems, along with tighter "relative" error bounds; - dynamical systems interpretations of some eigenvalue algorithms. Demmel discusses several current research topics, making students aware of both the lively research taking place and connections to other parts of numerical analysis, mathematics, and computer science. Some of this material is developed in questions at the end of each chapter, which are marked Easy, Medium, or Hard according to their difficulty. Some questions are straightforward, supplying proofs of lemmas used in the text. Others are more difficult theoretical or computing problems. Questions involving significant amounts of programming are marked Programming. The computing questions mainly involve Matlab programming, and others involve retrieving, using, and perhaps modifying LAPACK code from NETLIB.

Availability of Real World Data The U.S. Navy has completed an experimental program which involved collection of helicopter drivetrain data under a variety of normal and seed-fault conditions that are intended to emulate real-world scenarios. This data, which has been made available on the world wide web offers a unique opportunity for an in-depth cross-disciplinary study of a real-world problem of national concern. All extended abstracts must include preliminary, but meaningful analysis of a portion of this data set to receive due consideration. Web Site Information The a subset of the data is available at the Penn State web address: http://wisdom.arl.psu.edu/Westland/data/data.htm This site also includes a description of the tests, and a report. The above information is also available in a CD format. To request a CD contact Dave Hall at the email address: dlh28@psu.edu. The CD contains the same test conditions that are on the web site, but each condition includes 4 times the amount of data. Presenters The workshop will include a total of no more that 20 presenters. Of these, there will be two invited plenary speakers. One is Professor Simon Braun of the Technion Institute of Technology in Haifa, Israel. Professor Braun is the chief editor of Mechanical Systems & Signal Processing. He has consulted with a wide variety of U.S. automotive and manufacturing industries for over 30 years. The second is Mark Hollins of NAVAIR at the Patuxent U.S. Navy station. Mr. Hollins was responsible for the collection of the helicopter data. Other Attendees This workshop should be of interest to a variety of individuals, in addition to the presenters. Such individuals are strongly encouraged to attend, but they should realize that their input during the sessions must be limited due to time constraints. The workshop will be structured so as to encourage their interaction with workshop presenters and each other during session breaks and in evening social gatherings. Proceedings While presenter selection will be based on review of extended abstracts, all presenters will be required to submit a full paper within one month after the workshop. This will allow redress of issues brought up during the workshop, as well as for improved integration of the topics. These papers will be considered for inclusion in a special issue of the Academic Press journal Mechanical Systems & Signal Processing, which will serve as the conference proceedings. Workshop Schedule The workshop schedule will take place over 2.5 days. The important dates pertaining to the workshop are: 31 December 1997: Deadline for paper submissions of extended abstracts. 31 January 1998: Notification of acceptance/rejection. 26-28 March 1998: Workshop (2.5 days) 30 April 1998: Due date for full papers Venue The workshop venue has been tentatively identified as of this time. It will preceed the 52nd Meeting of the Society for Machinery Failure Prevention and Technology. This meeting is scheduled for 30 March - 2 April in Virginia Beach, VA. Cost of Attendance Each presenter will receive $500 to help defray travel and lodging expenses. This support will be in the form a reimbursement, and is conditional upon receipt of the full paper by the specified date. The cost for attendees other than presenters will be $150. Sponsors Support for this workshop is being provided by the Office of Naval Research, the Air Force Office of Scientific Research, and the Society of the MFPT (pending).

It is situated an the site of an 11th century city, Bhojapal, founded by Raja Bhoja. Bhopal has history and culture imprints all around the city. Hundreds of Mohgul age pieces of architecture which include Taj- ul-Masjid, Jama and Moti Masjid, shaukat Mahal and Mohar mahal are some of the monumental buildings. Bharat Bhawan, a center for visual and performing arts, houses a museum of tribal and folk arts, an art gallery, and a repertory theatre. The two lakes of Bhopal still dominate the city and are indeed its nucleus. Along their shores stand silent sentinels that testify to the growth of the city. Sanchi, adjacent to Bhopal is known for its stupas, monasteries, temples and pillars dating from the 3rd century BC to the 12th century AD. Carved with stories of the Buddhas life and incidents from the subsequent history of Buddhism, the monuments are the finest specimens of early classical art and formed the seedbed for the entire vocabulary of later indian art. *.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.*.** Contributed by: J. Rudolph (rudolph@erss11.et.tu-dresden.de) Seminar on Flatness Based Control A seminar on the flatness based control of nonlinear systems will be organized at the Institut fuer Regelungs-- und Steuerungstheorie Technische Universitaet Dresden, Germany on October 7 - 10, 1997 The flatness concept has been introduced by Fliess, Levine, Martin, and Rouchon in 1992. Since then it has been shown to be very helpful for the analysis and the control design of nonlinear systems that are flat. This property is shared by a large number of models in all fields of application. It is of particular advantage for the solution of motion planning and trajectory tracking problems. The aim of the present four days seminar is to give an introduction to the use of the flatness for the design of nonlinear control systems. Special attention will be paid to technological examples, which will be studied in courses and computer lessons. The extension to nonlinear systems with delays and linear systems with distributed parameters is discussed, too. Languages are English and German. Speakers: M. Fliess, J. Levine, R. Rothfuss, P. Rouchon, J.
