摘　　要：讨论了不确定性关联大系统的鲁棒故障检测问题,使残差信号和加权故障信号之间的误差最小,并对动态关联项、控制输入和系统的不确定性具有鲁棒性进行了探讨,应用线性矩阵不等式得到此类不确定性系统的鲁棒故障检测滤波器的存在条件.最后,给出了滤波器参数矩阵的数值解法.仿真例子说明了方法的有效性.To investigates the problem of robust fauh detection for a class of uncertain large - scale system, the ,bjective is to minimize the difference between the residual and the weighted fault and to enhance the robustness to dynamic interconnected terms ,control inputs and model uncertainties, The existence condition of the filter is established by means of linear matrix linear matrix inequalities. The given example shows the application of the method.
