Output Feedback Non-fragile Robust H∞ Control for Switched Systems with Multiple Time Delays

摘要

Since the parameters of system and controller are polytopically uncertain,this paper is devoted to the non-fragile robust H∞ control problem for the switched discrete time systems with multiple state and input time delays.Based on the state observer,the delay-dependent sufficient conditions are presented to guarantee the system asymptotically stable and having H∞ disturbance attenuation level under arbitrary switching signals.By employing the cone complementarity linearization algorithm,the design procedure is developed for output feedback non-fragile robust H∞ controller.The simulation results show the effectiveness of the proposed controller design method.
