Abstract
En 中文
This article focuses on the hybrid dynamic event-triggered control problem for networked control systems under denial-of-service (DoS) attacks. The signals are transmitted over sensor-controller-actuator networks subject to asynchronous DoS attacks, and only local information is available to the triggering generator, which leads to asynchronous transmissions. Scheduling protocols exist in each network channel to exclude data collision caused by limited bandwidth. A resilient hybrid dynamic event-triggered mechanism (HDETM) is proposed to enable systems to withstand a certain degree of DoS attacks. Based on the hybrid system framework, the whole system is described by a hybrid model. The explicit design of HDETM and the stabilization condition are given, which can ensure exponential stability and L-p-gain of the hybrid system. Moreover, Lipschitz nonlinear systems are presented as a case study in which the linear matrix inequality technique is utilized to formulate the design conditions. Finally, simulations of linear and nonlinear numerical examples are provided to demonstrate the effectiveness of the results.
