Announcing the Block Island Workshop on Control Using Logic-Based Switching at the Spring House Hotel on Block Island, Rhode Island September 29 - October 2, 1995 Supported by the National Science Foundation Army Research Office Yale University Faculty of Engineering Princeton University Department of Electrical Engineering The theme of this workshop is control using logic-based switching. 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. The workshop will be centered around approximately seventeen consecutive, 45 minute presentations given over a two day period. We are encouraging the attendance of individuals who are either already working in the area or who desire to learn more about opportunities for research in the area. 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 Speakers: M.
