Ramadge +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Contributed by Charles Herget THE 29TH IEEE CONFERENCE ON DECISION AND CONTROL Hilton Hawaiian Village Honolulu, Hawaii December 5-7, 1990 The IEEE Conference on Decision and Control (CDC) is the annual meeting of the IEEE Control Systems Society. It is conducted in cooperation with the Society for Industrial and Applied Mathematics (SIAM) and the Operations Research Society of America (ORSA). This year the Society of Instrument and Control Engineers of Japan will also be a participating society. The twenty-ninth CDC will be held on December 5-7, 1990, at the Hilton Hawaiian Village in Honolulu, Hawaii. The General Chairman of the Conference is Charles J. Herget of Lawrence Livermore National Laboratory. The Program Chairman is Raymond A. DeCarlo of Purdue University. The Conference will include both contributed and invited sessions. Papers and Sessions are hereby solicited in all aspects of the theory and application of systems involving decision, control, optimization and adaptation. CALL FOR CONTRIBUTED PAPERS The 29th CDC Program Committee is soliciting two types of papers for presentation at the Conference: a. Regular papers describing completed work in some detail. Authors should submit six (6) copies of the full paper for review. Each paper must be headed with the paper title, the names, affiliations and complete mailing addresses of all authors, and the statement "29th CDC". The first named author will be used for all correspondence unless otherwise requested. A regular conference paper may simultaneously be submitted for possible publication as a regular paper in the IEEE Transactions on Automatic Control if requested and if a total of seven (7) copies is submitted for review. Please consult the Information for Authors which appears in each issue of the Transactions. Submission must be made no later than March 1, 1990, to: 29th CDC Professor N. H. McClamroch Dept. of Aerospace Engineering University of Michigan 2508 Patterson Place Ann Arbor, MI 48109-2140 (313) 763-9304 mcclamroch@um.cc.umich.edu b. Short papers that present important recent or perhaps preliminary results. Authors should submit four (4) copies of a 4-6 page detailed summary (plus references) for review. Each summary must be headed with the paper title, the names, affiliations and complete mailing addresses of all authors, and the statement "29th CDC". The first named author will be used for all correspondence unless otherwise requested. Submission must be made no later than March 1, 1990, to: 29th CDC Professor Raymond A. DeCarlo School of Electrical Engineering Purdue University West Lafayette, IN 47907 (317) 494-6389 decarlo@ee.ecn.purdue.edu Authors will be notified regarding acceptance of their papers for presentation at the CDC by JUNE 20, 1990. Authors of accepted papers will be provided with publication kits and instructions for preparing their manuscripts for the Proceedings. In particular, authors will be requested to keep their manuscripts to six Proceedings pages or less (about 6,000 words). Short papers will be limited to two Proceedings pages (about 2,000 words). There is a mandatory page charge for each additional page. Authors of accepted papers are expected to attend the Conference to present their work. CALL FOR INVITED SESSIONS The 29th CDC Program Committee is also soliciting proposals for invited sessions. The Program Committee particularly encourages cohesive sessions focusing on new emerging areas and sessions built around theme problems. Mainstream or classical topic papers should be submitted as contributed papers. Proposals should be submitted by MARCH 1, 1990, to the CDC Program Chairman, Professor Raymond A. DeCarlo, whose address is given above. Proposals for invited sessions should contain the session chairperson, co-chairperson, a complete list of authors, everyone's address, paper titles, abstracts, and detailed extended summaries. The organizers must include in their proposal: (i) a clear statement on the topic and the purpose of the session, (ii) a clear statement on the importance/relevance of the topic to the field, and (iii) a reasonably detailed description of how the papers form a cohesive, well integrated exploration of the session topic. The detailed extended summaries must be a minimum of 2000 words covering all contributions of the paper in sufficient depth to permit informed review. Organizers are encouraged to consider launching a session with a tutorial/survey paper/presentation which can be allotted twice the time accorded to regular papers. Final selection of invited sesisons will be announced by June 20, 1990. CALL FOR SPECIAL TECHNICAL SESSIONS The Committee also invites proposals for technical sessions on topics for which it is most effective to have the audience converse with the author while standing close to view displays of computer terminals, video tapes, diagrams and/or photos/posters. Proposals should be submitted by MARCH 1, 1990, to the CDC Program Chairman, Professor Raymond A. DeCarlo, whose address is given above. The organizers will be contacted before May 5, 1990, concerning the tentative disposition of their sessions. Additional information may be requested at that time. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Contributed by tbasar@markov.csl.uiuc.edu THE 1989 GEORGE S. AXELBY OUTSTANDING PAPER AWARD (covering the period January 1987 - December 1988) The George S. Axelby Outstanding Paper Award is awarded each year by the Control Systems Society to the authors of outstanding papers published in the IEEE Transactions on Automatic Control during the two calendar years preceding the year of the Award. At most three papers can be selected each year. Papers are judged on their originality, their potential impact on the foundations of control, their importance and practical significance in applications, and on their clarity. Nominations for the Award for the year 1989 were solicited through announcements in the IEEE Control Systems Magazine, the AC Transactions, and the Electronic Newsletter, as well as by directly contacting the members of the Editorial Board of the Transactions. The submissions were then evaluated by an international panel of authorities in the field. As a result of this process, the following two papers were selected to receive this prestigious Award in 1989: Munther A. Dahleh and J.Boyd Pearson, Jr., ``l^1-Optimal Feedback Controllers for MIMO Discrete-Time Systems,'' vol. AC-32, no.4, pp. 314-322, April 1987. Hassan K. Khalil, ``Output Feedback Control of Linear Two-Time-Scale Systems,'' vol. AC-32, no.4, pp. 784-792, September 1987. Prof. Dahleh is currently with the Massachusetts Institute of Technology, Cambridge, Massachusetts, and Prof. Pearson is with Rice University, Houston, Texas. Their paper addresses the problem of designing a closed-loop system consisting of a MIMO discrete-time plant and a compensator in such a way that the system is internally stable and optimally tracks all persistent bounded (instead of energy bounded) inputs. The performance here is measured by the maximum value of the error, under which the authors present a very clean solution to the problem. They show that the design problem reduces to one of solving a linear programming problem, which makes the solution very practical in addition to being theoretically complete. Prof. Khalil, is with the Michigan State University, East Lansing, Michigan. His paper is on the design of output feedback controllers for linear systems with slow and fast dynamics. Working in the frequency domain, the author obtains a parametrization of all stabilizing compensators that preserve the two-time-scale properties of the original open-loop system. He then shows that these stabilizing compensators can be approximated by a composite compensator designed in two stages: a high frequency compensator to stabilize the fast model of the system, and a strictly proper low-frequency compensator to stabilize a modified slow model. In addition to the novelty of the theoretical approach, the paper is also considered to make a major impact on the practical design of compensators for systems which exhibit time-scale separation. NOMINATIONS FOR THE 1990 GEORGE S. AXELBY OUTSTANDING PAPER AWARD Nominations covering the period January 1988 - December 1989, are already OPEN.

If you have or know of any such problems, please send them to us; references to the literature and unpublished problems are welcome. We'd also welcome email or conventional addresses of other researchers who may have example problems. The form the problems should have (or be transformable to) is simple and quite general: a linear system with a constant diagonal feedback around it; the entries of the diagonal matrix are the parameters. There can be equality constraints among the parameters, which lie between given upper and lower bounds, l_i < f_i < u_i. This form includes, for example, systems of the form x dot = A(f)x, where the entries of A(f) are polynomials of the parameter vector f. Broad categories of problems that we solicit are: Kharitonov examples, and examples based on polytopes of polynomials (we have made up a number of each). Examples with a known Lyapunov fct. that proves robust stability (we have a few examples of mechanical systems; the parameters are physical spring constants, masses, lengths etc). Interval matrix problems. "mu", or even better, "real mu" problems. Examples used by other researchers to try other algorithms (and thus, have known solutions or upper/lower bounds). Possibly even real-world problems. If other researchers can send us reasonable code, we'd be happy to test theirs on the problems we have or collect. "Reasonable" means: developed under a Berkeley type UNIX, with makefile and README file. If there is interest, we will make the problems we collect available to other researchers. Thanks, S.

Boyd and V. Balakrishnan Information Systems Laboratory, Electrical Engineering Department, Stanford University, Stanford, CA 94305. Abstract The $i$th singular value of a transfer matrix, $\sigma_i(H(j \omega ))$, need not be a differentiable function of $\omega$ at frequencies where its multiplicity is greater than one. We show, however, that near a local maximum, the largest singular value $\sigma_1(H(j \omega ))$ has a Lipschitz second derivative, but need not have a third derivative. Based on this regularity result, we present a quadratically convergent algorithm for computing the ${\bf L}_{\infty}$-norm of a transfer matrix. Copies available from: S.

EMAIL:BC@SIGURD.SUNET.SE Recent Ph.D. thesis in Digital Signal Processing entitled: DIGITAL DIFFERENTIATING FILTERS AND MODEL BASED FAULT DETECTION By Bengt Carlsson Automatic Control and Systems Analysis Group Department of Technology, Uppsala University Box 534, S-751 21 Uppsala, Sweden. ABSTRACT Carlsson, B., 1989. Digital Differentiating Filters and Model Based Fault Detection. Acta Univ. Ups., Uppsala Dissertations from the Faculty of Science 28, 215pp. Uppsala. ISBN 91-554-2473-2. This thesis treats two problems in digital signal processing: estimation of the derivative of a noise corrupted signal from discrete-time measurements and the detection of faults in a dynamical system using an estimated model. The first part of the thesis is devoted to the design of digital differentiating filters. General design strategies and characterizations of differentiating filters are outlined. A design technique for constructing digital differentiating filters based on stochastic signal and noise models is presented. IIR-filters which minimize the mean square estimation error are calculated from a spectral factorization and a linear polynomial equation. The filters can be designed for prediction, filtering and smoothing problems. Furthermore, a method for optimizing differentiating FIR-filters in the frequency domain is presented. Illustrations and comparisons with other methods are provided. The problem of tracking step changes in the true derivative is also studied. Methods for detecting parameter changes are investigated and applied to the differentiation problem. In a practical application, the temperature derivative of a reactor tank in a nuclear power plant is estimated by a simple adaptive filter. The second part of the thesis describes some approaches to off-line fault detection based on estimated models. In practice, the estimated model is subject to errors due to measurement noise and model misfit. Some statistical tests based on standard asymptotic theory for system identification are compared and illustrated. Two cases of model misfit are discussed: nonparametric static nonlinearities and unmodelled linear dynamics. A proposal for a fault detection procedure which accounts for undermodelling is given. A number of copies of the thesis are available for distribution.
