4 . with the result of the fault diagnosis of the unit coordinated control system , a new scheme of active fault tolerant control is proposed . the tolerant control is realized through reconfiguring the control law . the effectiveness of the fault diagnosis and fault tolerant control scheme presented is show by the simulation result 提出了多模型自适应滤波的故障诊断的新方案,本方案主要是利用卡尔曼滤波器阵列实现多模型自适应滤波,实现故障的诊断,通过大量仿真验证了故障诊断算法的有效性。
