Dynamic Event-Triggered Control of Continuous-Time Systems With Random Impulses

In this paper, the networked control problem under event-triggered schemes is considered for a class of continuoustime linear systems with random impulses. In order to save communication costs and lighten communication burden, a dynamic event-triggered scheme whose threshold parameter is dynamically adjusted by a given evolutionary rule, is employed to manage the transmission of data packets. Moreover, the evolution of the threshold parameter only depends on the sampled measurement output, and hence eliminates the influence of impulsive signals on the event-triggered mechanism. Then, with the help of a stochastic analysis method and Lyapunov theory, the existence conditions of desired controller gains are received to guarantee the corresponding input-to-state stability of the addressed system.Furthermore, according to the semi-definite programming property, the desired controller gains are calculated by resorting to the solution of three linear matrix inequalities. In the end, the feasibility and validity of the developed control strategy are verified by a simulation example.
