| 摘 要： | 对一类离散时间线性时不变系统,研究当执行机构发生连续增益故障情况下的可靠保性能状态反馈控制律的设计问题.应用线性矩阵不等式处理方法,导出系统存在可靠保性能控制律的一个充分条件,进而用一个线性矩阵不等式的可行解给出所有可靠保性能控制律的一个参数化表示.在此基础上,通过建立和求解由一组线性矩阵不等式所表示的凸优化问题,得到最优可靠保性能控制律的设计方法.

| Abstract: | This paper is concerned with the reliable guaranteed cost state feedback control problem for discrete-time systems with actuator failures.A sufficient condition for the existence of reliable guaranteed cost controllers is derived via the linear matrix inequality(LMI) approach.And the design of the optimal reliable guaranteed cost controller is formulated as a convex optimization problem,which can be solved by the existing convex optimization techniques. |
