Abstract: The secure output regulation (OR) is studied for networked switched systems (NSSs) that exhibit severely unstable dynamics (SUDs) and are vulnerable to multiple deception attacks. The occurrence of some destabilizing switching and unsolvable OR of each individual subsystem is permitted. Dual distributed event-triggered mechanisms (DDETMs) are proposed, incorporating both distributed event detection conditions to tackle the issue of unreliable single-channel data during deception attacks on sensor networks, and mode-matching detection conditions to reduce asynchronous intervals. A dwell time switching rule is developed without consistency constraint, i.e., the sub-controller's stabilizing/destabilizing switching may be inconsistent with that of the subsystem. Judging conditions are introduced for the occurrence of multiple deception attacks on dual-terminal sensor/transmission networks, which adjust the increment coefficients of Lyapunov functions before or after switching instants. Sufficient conditions are provided to ensure secure OR for NSSs under multiple deception attacks. With the aid of a switched RLC circuit, the effectiveness of the presented methodologies is validated.
