摘要

针对状态时滞随机系统，应用事件驱动近似二次性能指标和随机均方有界理论，同时考虑控制输入和事件决策，设计了反馈控制器和相应的事件驱动控制策略.基于状态反馈的事件驱动策略同时使用当前状态和时滞状态进行事件的触发，并利用近似二次性能指标进行约束；基于输出反馈的事件驱动策略使用当前状态进行事件的触发.最后，通过实验进行了仿真，对事件驱动性能指标进行量化，并与相关文献进行对比，验证了所提出方案可以在保证系统性能的前提下有效减少通信传输，延长无线传感网络的使用寿命.

Abstract

This paper is concerned with the event-triggered controller and the corresponding event transmission rule for a class of stochastic system subject to state delay. The basic theories are approximate quadratic performance index and mean-square boundedness theory. First

the event-triggered state feedback control scheme constrained by the approximate quadratic performance index is proposed which used the current state and time-delay state simultaneously. Subsequently

an event-triggered output feedback control scheme is established which eliminates the influence of the state-delay terms according to the mean-square boundedness theory. Finally

a numerical example is given to illustrate the effectiveness of the proposed strategies.
