| 摘 要： | 讨论了执行器故障下，线性不确定时滞系统的可靠保成本控制问题。提出了更实际、更一般的执行器故障模型；给出了以LMI表达的故障系统渐近隐定以及成本函数有上界的充分条件；进一步对执行器故障情况下的成本函数上界进行了优化，该优化是通过一个LMI组的最小化问题来实现的，对扰动输入具有一定的衰减性能。仿真实例验证了所得结果的有效性。

| Abstract: | The problem of reliable guaranteed cost control system desin is disscussed for linear uncertain time-delay systems with actuator failures.A more practical and general model of actuator failures is presented.Based on linear matrix inequality approach,sufficient conditions for robust asymptotically stable and cost function index owns upper bounded of linear uncertain time-delay fault systems are setted up.Furthermore,a convex optimization problem with LMIs constraints is formulated to design the optimal reliable guaranteed cost controller.A simulation example shows the efficiency and necessity of the design method. |
