摘要

This paper focuses on the synchronization issue of impulsive switched complex networks (ISCNs) with two asynchronous behaviors under denial-of-service (DoS) attacks and actuator faults via event-triggered control. DoS attacks are allowed to strike both the sensor-controller channel and the controller-actuator channel simultaneously. Regarding this trait, the novel double mode-dependent adaptive event-triggered mechanisms (ETMs) incorporating DoS information are developed on account of sampling technique. These ETMs not only compensate for the destructive power of DoS attacks, but also save communication resources and control consumption. Further, the constrained switching and impulse are designed. Especially, they combine the transition probability, admissible edge-dependent average dwell time (AED-ADT), and admissible edge-dependent average impulsive interval (AED-AII) to jointly adjust switching and impulsive signals, offering more flexibility and versatility. Lyapunov-based sufficient conditions for synchronization of the system and the quantitative relationship between switching signal, impulsive signal, and DoS attacks are created. Additionally, the gains of the corresponding state feedback controllers are derived. Finally, the validity of the obtained results in practical applications is demonstrated through the examples of single-link robot arms and Chua’s circuit.
