| 摘 要： | 研究了在干扰存在情况下基于全维PI观测器的混沌系统鲁棒故障检测设计问题。基于一类Sylvester矩阵方程的参数化解,给出了干扰和残差信号解耦的充要条件,并建立了具有鲁棒故障检测功能的全维PI观测器设计的参数化方法。Lorenz混沌系统的数值算例及其计算结果表明：在干扰存在的情况下,基于全维PI观测器的混沌系统鲁棒故障检测设计方法简单有效。

| Abstract: | The design problem of robust fault detection via full-order PI observers in chaotic systems with disturbances is investigated.Based on the parametric solutions of a class of Sylvester matrix equations,the necessary and sufficient condition that can decouple the disturbance signal from the residual signals is proposed and a parameterized design method of full-order PI observers with the robust fault detection function is established.Finally,a numerical example about a Lorenz chaotic system and its computation results show that the design method of robust fault detection via full-order PI observers in chaotic systems with disturbances is simple and effective. |
