Dynamic Output Feedback Control and Guaranteed Cost Finite-time Boundedness for Uncertain Switched Linear Systems

摘要

This paper is concerned with dynamic quantized output feedback and event-triggered guaranteed cost finite-time H-infinity control for uncertain switched linear systems with exogenous disturbance. First, one mode-dependent periodic event-triggered strategy is designed, which means that each subsystem has its own event-triggered mechanism. Meanwhile, the periodic detection of the error greatly reduces the sampling number and avoids the appearance of Zeno behavior. Second, considering the state information of the system is difficult to obtain completely, dynamic quantized output feedback controllers based on logarithmic quantizer are used to stabilize the switched system. Besides, combine the multiple Lyapunov functionals and the average dwell time condition, the sufficient condition of finite-time boundedness with H-infinity performance level is obtained for the uncertain switched system. Finally, the effectiveness of the proposed method is verified a practical example.
