Abstract :
The fault detection problem is investigated for the morphing flight vehicle with different switched sweepback during flight. First, the flight dynamics is modeled as a switched system based on the theory of the multi-rigid-body and switched system. Then, the discrete model is presented by the theory of stochastic control theory. Also, the robust fault detection filter for the discrete switched control system is designed with H_/H∞ performance index. Depending on multiple Lyapunov function and the average dwell-time method, we analyze the system stability and the sufficient existing conditions of filtered are derived in the form of LMIs. Finally, numerical examples based on Fire-Bee morphing flight vehicle are given to illustrate the efficiency of the proposed method.
