Design of H∞ Control Strategies With Dynamic Event-triggered Scheme Under Markovian Deception Attacks
摘要
This paper presents a dynamic event-triggered output feedback controller for networked control systems under Markovian deception attacks. A dynamic event-triggered scheme is applied to curtail redundant sensor-to-observer data transfers. Given the prevalence of deception attacks in network signal transmission, these are modeled by a Markov process, and construct an augmented system. Utilizing Lyapunov stability theory, conditions are established for the system’s asymptotic stability. Controller gains and event-triggering parameters are derived through the solution of linear matrix inequalities. Simulation results substantiate the controller’s effectiveness in countering the impacts of network attacks on the NCSs.
