多重模型自适应滤波的故障诊断与容错

AN APPROACH TO FAILURE DIAGNOSIS AND FAULT TOLERANCE WITH MMAF

对多重模型自适应滤波（ＭＭＡＦ）进行了改进并将它用于控制系统的传感器的故障诊断与容错。数值仿真表明，其故障诊断准确度高，容错效果良好。

A modified approach of MMAF (multiple mo del adaptive filter) to failure diagnosi s and fault tolerance for aero engine co ntrol system is presented.This method is very simple and the prior knowledge abo ut threshold is not necessary.The simula tion shows this method can detect more r eliably and less time than Kalmans appr oach is needed.
