IMPROVING TRANSIENT-RESPONSE OF ADAPTIVE-CONTROL SYSTEMS USING MULTIPLE MODELS AND SWITCHING

A well-known problem in adaptive control is the poor transient respons e which is observed when adaptation is initiated. In this paper we dev elop a stable strategy for improving the transient response by using m ultiple models of the plant to be controlled and switching between the m. The models are identical except for initial estimates of the unknow n plant parameters. The control to be applied is determined at every i nstant by the model which best approximates the plant. Simulation resu lts are presented to indicate the improvement in performance that can be achieved.
