This paper is concerned with event-triggered H∞ control of sampled-data systems.Its novelties lie in three aspects:(ⅰ)A novel accumulated-state-error-based event-triggered scheme is introduced by com-paring the integral of the state error fromtkto t with the system state sampled at tk.This condition works well due to the fact that the so-called Zeno behaviour does not occur.(ⅱ)A novel Lyapunov functional is constructed to establish a criterion to ensure some certain H∞ performance of the closed-loop system.This Lyapunov functional is dependent on the integral of the state error involved in the event-triggered scheme.(ⅲ)Under the event-triggered sampling scheme,suitable state-feedback controllers can be designed rather than be given a priori.Moreover,a self-triggered implementation of the proposed event-triggered sampling scheme is presented as well.Finally,a batch reactor model and an inverted pendulum system are given to demonstrate the effectiveness of the proposed method.
