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.
从无源观点出发，解决了网络切换系统（NSS）在存在欺骗攻击（DA）时允许严重不稳定动态的安全输出调节（SOR）问题。开发了双双层事件触发策略（DLETP），以结合无源、DA和切换特性的参数以分层方式控制适当的触发。提出了一种容错切换策略（TSS），以允许不稳定切换的数量超过稳定切换的数量并捕获无源参数。在NSS的SOR中DLETP和TSS的联合设计中，通过系统的无源程度展示了系统稳定性、候选李雅普诺夫函数、受DA影响的事件触发和切换行为之间的直接量化联系。航空发动机模型速度调节的仿真结果证明了所提出控制方法的有效性。
