| 摘 要： | 针对一类具有状态时滞和参数不确定性的不确定关联时滞大系统 ,提出了一种基于状态观测器的鲁棒可靠控制器设计方法。该方法通过求解一组线性矩阵不等式 (LMI) ,给出状态观测器和线性动态输出反馈控制器的设计方法。该控制器对于系统中任意容许的不确定性以及在每一个子系统中预先指定的执行器子集合执行器的失效 ,都可以镇定相应的闭环系统。通过仿真实验证明该设计方法的有效性。

| Abstract: | The design methods of robust reliable control for a class of large scale interconnected uncertain system with time-delay are proposed. The system under consideration involves state time delay and parameter uncertainties. The linear matrix inequality (LMI) approach is developed to design the state observer and linear dynamic output feedback controller such that, for all admissible uncertainties as well as actuator failures occurring among a prespecified subset of actuators, the closed-loop system is asymptotically stable. An illustrative example and simulation results are given to demonstrate the effectiveness of the proposed design methods. |
