摘　　要：对一类具有多时滞的不确定线性随机系统,研究了保性能状态反馈控制律的设计问题。采用线性矩阵不等式方法和伊藤公式,导出了保性能控制律的存在条件。进而,通过设计一个线性无记忆的状态反馈控制器,使得对于所有系统容许的不确定,闭环系统是范数有界的。最后用数值例子说明了该方法的有效性。The problem of designing state feedback guaranteed cost control laws is studied for a class of uncertain linear time-delay stochastic systems. By using the linear matrix inequality approach,the existence conditions are derived and a guaranteed cost controllers is presented. Furthermore,Design a linear memoryless state feedback controller such that all systems allow for the uncertain closed-loop system is norm bounded.
