This page contains references to several results in this relatively new area. The WWW address of this page is: http://eewww.eng.ohio-state.edu/~tokero/comp.html "Complexity issues in dynamical systems" includes (but not limited to) NP-hardness/completeness, algorithmic unsolvability (including both by regular Turing machines, and by non-standard Turing machines), algebraic unsolvability (being not semialgebraic over Q, or over R), or any other type of complexity result about problems related with linear systems, nonlinear systems, discrete event/hybrid systems, or any other type of dynamical system. In summary, "Complexity issues in dynamical systems" includes any kind of complexity result about control/system theoretic problems.

The course is aimed at engineers and control practitioners providing practical knowledge and tools for design, analysis and implementation of both conventional and advanced control strategies. It would also be beneficial to academics or research students in gaining exposure to how modern control theory can be effectively applied to practical problems. The course features a problem based learning format where the material is motivated by and applied to real world problems, and then followed up by hands-on laboratory sessions.

The backlog that existed years ago has been completely cleared. For instance, several papers that were received in the second half of 1994 are already appearing in the 1995 volume. MCSS publishes one volume (four issues) per year, with about 400 pages. AIMS AND SCOPE MCSS publishes original and high-quality research papers concerned with mathematically rigorous, system theoretic aspects of control and signal processing. HANDLING OF PAPERS A paper is assigned to an Associate Editor, who makes a publication recommendation on the basis of a detailed and careful evaluation by two or more referees. Evaluation criteria used include originality, substance, and quality of exposition. To maintain the highest possible standards of quality, and to pursue the goal of timely publication, only a small fraction of submitted papers can be expected to be accepted. The journal strives for a fast turnaround in the review process. SUBMISSION A typical paper submitted to MCSS consists of an average of 20 pages of LaTeX in 12 point article style with a maximum of 25 such pages, 50 double-spaced typewritten pages, or the equivalent. If a paper is longer than the maximum number of pages then authors are requested to provide a justification for the added length in their cover letter. Associate Editors and reviewers are instructed to pay careful attention to conciseness as an important characteristic of good mathematical exposition. The address for submissions is: J.H. van Schuppen Co-Editor MCSS CWI P.O. Box 94079 1090 GB Amsterdam The Netherlands Authors wishing to inquire about the scope of the journal or the suitability of a particular topic are encouraged to contact the Editors informally, preferably by electronic mail, prior to submission. Email inquires regarding submission should be addressed to mcss@cwi.nl. WWW PAGES OF MCSS http://www.cwi.nl/cwi/departments/BS3/mcss.html http://www.math.rutgers.edu/~sontag/mcss.html These pages are identical; the access is faster to one of these depending on the geographical area from which the request originates. The MCSS Home Page provides general information on the journal, as well as information regarding the submission of manuscripts. Two additional pages can be accessed from the main page: - a page which provides information on the tables of contents of recently appeared issues of MCSS and on papers accepted for publication but not yet published; - and a page which provides information on the tables of contents of the older volumes of MCSS.

Theoretical achievements, such as H-inf optimisation, mu-synthesis and parametric optimisation, to name just a few, have emerged. Also encouraging is the extension of robust control techniques into the area of nonlinear systems. At the same time, many researchers have been working hard to apply the newly developed results to real, industrial projects. However, by and large, practising control engineers are still unfamiliar with these new theories and the accompanying design techniques. It is now important for researchers to demonstrate the successes of advanced robust control techniques to industry and to arouse interest among industrial control engineers. Therefore, it has been decided to organise a special issue of the "International Journal of Robust and Nonlinear Control" on Robust Control Applications. The theme of the special issue will be industrial applications of robust control methods. Applications may be in any industrial sector. The design methods are not limited either, and may include -- H-inf/H-2 optimisations -- Mu-synthesis -- Nonlinear finite L2-gain control -- Variable structure control -- Adaptive control -- Neural/fuzzy control, etc Papers describing significant and interesting applications are solicited for the special issue, which is scheduled for late 1996 or early 1997. Five copies of the manuscript should be submitted to Da-Wei Gu or Ian Postlethwaite by 1 January, 1996 for review. For contributor guidelines, please refer to a recent issue of the "International Journal of Robust and Nonlinear Control".

By a logic-based switching controller is meant a controller whose subsystems include not only familiar dynamical components such as integrators, summers, gains, etc., but a nontrivial logical component as well. More often than not the predominately logical component within such a system is called a supervisor, a mode changer, a gain scheduler, a reference governor or something similar. Within the past few years there has been a growing interest in determining what might be gained by utilizing hybrid controllers of this type. Toward this end detailed analyses, simulation studies and laboratory experiments of such systems have been initiated in a variety of disciplines including adaptive control, gain scheduling, control of nonholonomic systems, motion control, and the control of saturation constrained systems. The primary purpose of the workshop is to bring together a small number of specialists working within the area for the purpose of crystallizing concepts, problem formulations, and approaches. We will also encourage the attendance of a limited number additional individuals who are either already working in the area or who desire to learn more about opportunities for research in the area. Because of space constraints attendance is limited to approximately thirty-five individuals. The workshop will be centered around approximately fifteen consecutive, 45 minute invited presentations given over a two day period. Block Island is about 70 minutes by ferry off the coast of Rhode Island. The island can also be reached by air. Because of limited air and ferry connections, participants should plan to spend the nights of September 29, 30, and October 1 on the island. Those traveling from the west coast may prefer to spend the night of the 28th enroute. On the other hand is not difficult to travel from Block Island to any destination in North America within a single day . Partial List of Confirmed Participants: L. Bushnell P. Caines J. Chandra E.
