Distributed event-triggered sliding mode control of switched systems

This paper investigates the problem of distributed event-triggered sliding mode control (SMC) for switched systems with limited communication capacity. Moreover, the system output and switching signals are both considered to be sampled by distributed digital sensors, which may cause control delay and asynchronous switching. First of all, a novel distributed event-triggering scheme for switched systems is proposed to reduce bandwidth requirements. Then, a state observer is designed to estimate the system state via sampled system output with transmission delay. Based on the observed system state, a switched SMC law and corresponding switching law are designed to guarantee the exponential stability of the closed-loop system with H-infinity performance. Finally, an application example is given to illustrate the effectiveness of the proposed method. (C) 2018 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
