Adaptive control of a class of unknown switched linear systems with dwell time

Abstract

In this paper, we discuss the model reference adaptive control problem of switched linear systems with unknown switching signals and unknown parameters. We discuss state feedback and output feedback adaptive control for the switched systems. Variable structure based adaptive controllers are applied to the switched systems and error convergence and signal boundedness are shown for a class of switching signals. A sufficient condition for stability and error convergence of the output feedback switched system with unknown parameters is derived in terms of dwell time. Simulation results are provided to show the effect of switched systems with adaptive control.
