Summary: | This paper is concerned with event-based robust stabilization of uncertain networked control systems under quantization and denial-of-service (DoS) attacks. First, a novel event-triggered communication scheme is proposed to determine when to transmit the sensor’s current sampled-data if the period of the jamming signal is detected. Second, under the proposed event-triggered communication scheme, the resultant closed-loop system is modeled as a switched system with an artificial state delay, in which parameter uncertainty, quantization, and DoS jamming attacks are considered in a unified framework. Third, by introducing a time-varying piecewise Lyapunov–Krasovskii functional, a sufficient condition is derived to design desired event-based state feedback controllers so that the exponential stability can be ensured for the resultant closed-loop system subject to DoS jamming attacks. Moreover, several quantitative relationships among the sampling period, the jammer period, and the minimum allowable sleeping period of the jammer are established. Finally, two examples are given to illustrate the effectiveness of the proposed method. |
