Abstract: We deal with event-triggered H_∞ 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 H_∞ performance index and reduces the number of transmitted signals. Numerical examples are given to show the efficiency of our method.

摘要：针对具有执行器饱和的离散时间分段仿射系统，提出一种事件触发控制器设计方法。考虑饱和信息，提出一种新的事件触发策略，该策略能节省通信资源。基于分段李雅普诺夫函数，推导出基于线性矩阵不等式的可行性条件。该条件不仅能保证闭环系统在一定H_∞性能指标下的稳定性，还能减少信号传输数量。最后，利用仿真实例验证该方法的有效性。

关键词组：事件触发控制；分段仿射系统；线性矩阵不等式；执行器饱和；H_∞性能
