基于影响矩阵的故障诊断方法及其在航空航天领域的应用

RESEARCH ON THE METHOD OF EFFECTIVE MATRIX BASED DIAGNOSIS AND ITS APPLICATION IN THE FIELD OF AERONAUTICS AND ASTRONAUTICS

提出了系统影响矩阵的概念，在此基础上提出了故障诊断的一种新方法——基于影响矩阵的诊断方法。该方法的核心是系统影响方程和系统测量方程。系统测量方程描述系统的输出（测量）特性；影响方程描述系统的各部件对各输出（测量）的影响特性。该方法能将测量信号的分析处理和故障的定位很好地结合起来。

A concept of system effective matrix is presented, and subsequently, a new method-effective matrix based diagnosis is given. The kernel of this method consists in system measuring equations and system effective equation. The former describes the behavior and output (measuring) of the system. The latter describes the effectiveness of the system components. The signal analysis and process can be conveniently combined with the faults location by this method.
