Adaptive fuzzy sliding-mode controller for BTT missile

In this paper, a novel adaptive fuzzy sliding mode controller for BTT missile is proposed, which incorporates the auto-tuning fuzzy logic system to sliding-mode control, the influence of the uncertainty of parameters can be alleviated. Besides, Lyapunov stability theorem is used to prove the stability of the system and the adaptive laws are deduced which possess the characteristics of sliding-mode control. Finally, the correctness and effectiveness of the method have been verified by simulation using nonlinear overload model of pitch channel of some BTT missile.
