摘　　要：We deal with event-triggered Hoo controller design for discrete-time piecewise-affine systems subject to actuator saturation.By considering saturation information,a novel event-triggered strategy is proposed to conserve communication resources.A linear matrix inequality based condition is derived based on a piecewise Lyapunov function.This condition guarantees the stability of the closed-loop system with a certain Hoo performance index and reduces the number of transmitted signals.Numerical examples are given to show the efficiency of our method.
