Abstract
This article investigates the event-triggered multisource bumpless transfer (MSBT) control problem of networked switched systems (NSSs) with the almost output regulation (AOR) performance subject to switching deception attacks (SDAs). First, an improved dwell-time approach is developed to derive a proper switching law and ensure the feasibility of the AOR for NSSs allowing the AOR of each subsystem unsolvable and some switching instants destabilizing (i.e., with Lyapunov function increments), where destabilizing and stabilizing switching instants are subsystem independent. Second, a novel description of deception attacks called SDAs is established that contains multiple attack functions switching based on the currently activated subsystem, which considers the characteristics of NSSs and can cause the most severe damage to system control performance. Due to the networks and the event-triggered scheme, the switching of SDAs does not coincide with the switching of subsystems and controllers, which pose a challenge to system analysis. Third, MSBT controllers are designed to suppress the control bumps induced by multiple sources, including asynchronous controller switching, event-triggering mechanism, and SDAs. Finally, an application to a switched resistance–inductor–capacitance circuit is given to verify the effectiveness of the proposed method.
