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 .
