Double-layer event-triggered policy of passivity-based output regulation under deception attacks for switched systems

Abstract

The problem of secure output regulation (SOR) is solved from the passivity viewpoint for the networked switched system (NSS) permitting severely unstable dynamics in the presence of deception attacks (DAs). Dual Double-layer event-triggered policies (DLETPs) are developed to govern the appropriate triggering in a layered manner in conjunction with parameters of passivity, DAs, and switching characteristics. A tolerant switching strategy (TSS) is proposed to permit destabilizing switching outnumbers stabilizing switching and capture the passivity parameter. In the joint design of DLETPs and TSS in SOR for NSSs, the direct quantificational connections are showcased between the system’s stability, candidate Lyapunov function, event-triggering subject to DAs, and switching behaviors through the system’s passivity degree. Simulation results of speed regulation for an aero-engine model provide the effectiveness of the presented control methodology.
