Abstract:
With AFOSR support, a new strategy called cyclic switching has been devised for dealing with the well-know, long standing, certainty equivalence control synthesis problem which arises in the design of identifier-based adaptive controllers because of the existence of points in the parameter space where the design model upon which certainty equivalence synthesis is based, loses stabilizability. The concept is provably correct, easily implemented, and applicable to both siso and mimo linear systems, whether they are minimum phase or not. The feasibility has been established of an entirely new method of supervisory control called dwell-time switching. Dwell time switching is a simple on-line logic capable of determining in real time which controller from a family should be put in feedback with a process as to achieve satisfactory performance. The method is intended to be used in situations where there is substantial process model uncertainty, so much in fact that no single fixed parameter, linear control can possibly work.
