摘　　要：针对一类离散化不确定马尔可夫跳变系统,研究了基于事件触发机制的保性能控制问题.首先假设不确定的参数是有界的,与传统的周期触发方式的区别是,事件触发机制可以判断采样信号是否需要传输.其次,利用时间间隔分析法,把事件触发机制和网络时延构造成一个时滞系统,根据时滞分析法,提出了事件触发条件和保性能控制器的协同设计方案.最后,用一个仿真例子验证此算法的有效性.The problem of event-triggered guaranteed cost control for uncertain networked discrete Markov jump systems is presented in this study.First,the parameter uncertainty is assumed to be norm-bounded.Different from the traditional time-triggered scheme,a discrete event-triggered scheme is used to determine whether the sampled data should be transmitted or not.Second,the time interval analysis approach is used to transform the system,i.e.,the event-triggered scheme and network-induced delays,into a time-delay system.On the basis of the time-delay system analysis method,an algorithm is derived to codesign the event-triggered conditions and guaranteed cost controller.Finally,an illustrative example is given to show that the proposed analysis and design techniques are effective.
