Dynamic Event-Triggered Sliding Mode Control for Interconnected Systems Under Unreliable Markov Communication Networks Vulnerable to Attacks

초록

This work studies the decentralized sliding mode control problem for interconnected systems based on a dynamic event-triggered transmission mechanism. To model unreliable communication networks that are susceptible to both energy-limited denial-of-service (DoS) attacks and transmission failures, a Markov model is adopted. A decentralized dynamic event-triggered mechanism is introduced to efficiently utilize limited channel resources by regulating data transmission based on system measurement outputs. Moreover, a hidden Markov model is used to estimate the working operation of the network transmission channel such that a hidden Markov model-based sliding mode controller can be designed by using the output feedback control method. By constructing a Lyapunov function, sufficient conditions are deduced to ensure the stochastic stability of the system and the reachability of the specified sliding mode surface, and a solvable criterion for obtaining the hidden Markov model-based sliding mode controller gains is presented. Finally, simulation results of a four-area interconnected power system are presented to demonstrate the effectiveness of the proposed method. © 2014 IEEE.
