Secure Control of Networked Switched Systems with Random DoS Attacks via Event-triggered Approach

Yonghui Liu

Abstract

This paper considers security control of networked switched systems in which the denial-of-service attacks may happen when the output information is transmitted from the sensor to the controller. Besides, it is assumed that the denial-of-service obeys Bernoulli distribution. First, to reduce the communication burden and retaining a satisfactory performance, an event-triggered sampling mechanism is adopted. And then, security control of the switched systems is analyzed by designing an output-feedback controller and a switching signal based on the average dwell time method. It is shown that the state trajectory can be driven onto a certain bound despite the presence of the random denial-of-service attacks. Finally, a numerical example is given to demonstrate the effectiveness of the proposed method.
