Abstract
This paper focuses on the problem of $H_{\infty}$ controller design of event-triggered networked control systems (NCSs) under quantization and Denial-of-Service attacks. Firstly, a new event-triggering transmission scheme is proposed, in order to lighten the load of computing and communications, while offsetting DoS attacks. A unified model containing event-triggering mechanism, quantization and DoS attacks is established by using time delay modeling approach. Then the sufficient conditions can be obtained for ensuring the exponential stability of the system under quantization and DoS attacks by using the time-varying Lyapunov functional method. The co-design of the event-triggering parameters and the controller parameter of the controller are obtained. Finally a simulation example is used to prove the effectiveness and feasibility of the obtained results.
