鲁棒故障检测H_∞滤波器的LMI设计方法研究

LMI-Based Method of Designing Robust Fault Detection H_∞ Filter

文中首先给出了输出反馈H_∞控制器的LMI求解方法。在此基础上,将鲁棒故障检测滤波器的设计规范成为鲁棒综合问题,从而给出了故障检测滤波器存在的充分必要条件和参数化的求解方法。仿真结果表明,该设计方法的有效性。

This paper first introduces the LMI-based method of designing output-feedback H_∞controller.Based on this the design of robust fault detection filter can be described as robust synthesis problem and the sufficient condition and parameterized solution are also given.Through the simulation the results shows this method valid.
