Dynamic Memory Event-Triggered Anti-Disturbance Control for Switched Cyber-Physical Systems and Its Application to Switched RLC Circuit

This article addresses the dynamic memory event-triggered anti-disturbance (DMETAD) control problem for switched cyber-physical systems (SCPSs) under the scenario of multiple disturbances and periodic Denial-of-Service (DoS) attacks. The multiple disturbances are composed by modeled disturbance and unmodeled disturbance. The control objective is to mitigate the impact of multiple disturbances and periodic DoS attacks. Firstly, the dynamic memory event-triggered (DMET) mechanism is introduced. Then, the disturbance observer is designed to estimate the modeled disturbance. Further, the controller based on the disturbance observer and DMET protocol is constructed to compensate the modeled disturbance and suppress the unmodeled disturbance. Next, by virtue of the multiple Lyapunov functions strategy, constraints are established for the SCPSs to force the solvability of the DMETAD control issue. Finally, a switched RLC circuit system simulation case is implemented, validating the reasonability of the established DMETAD control technique.
