Abstract: 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.
