Abstract:
Aimed at the complex flight control system of a fighter, a kind of robust adapti ve control methods using multiple models is presented to make the control system track the given signal under different working conditions and to reconfigure th e control law for some structural failures. Firstly, the multiplemodel control structure is formed by several linear models and one fuzzy model. In the fuzzy logic way, weights of the multiplemodel adaptive controller are obtained. Then , a dynamic structure adaptive neural network is introduced to stabilize the who le system and eliminate the influence caused by the frequent switching. Simulati on results show that the control method is effective by demonstrating the normal flight process and the control simulation with failures.
