歼击机结构故障的检测与自修复控制律重构

METHODS OF STRUCTURE FAULT DETECTION AND RECONFIGURATION OF SELF REPAIRING CONTROL LAW FOR A FIGHTER

针对鲁棒动态逆控制的飞机，提出一种有效的故障检测新方法及自修复控制律重构方法。设计了一种基于理想模型的非线性故障检测器，通过监测残差信号，能够可靠地对各类故障进行辨识，并利用补偿信号来抵消故障舵面产生的影响，可以满足自修复飞行控制的实时性要求。

A new efficient method of fault detection and method of reconfiguration of self repairing control law for a fighter controlled by robust dynamic inversion are presented. A nonlinear fault detector based on an ideal model is designed, where, by monitoring the signal is used error, reliable identification can be achieved for all sorts of failure and a compensating signal is used to offset the effect of the destroyed control surface. It can satisfy the real time demand of the self repairing flight control.
