Abstract: The paper presented a new adaptive fuzzy basis function (FBFN) controller for bank-to-turn(BTT) missile, which is a complicate nonlinear plant. Method FBFN was used as a universal approximator to achieve the ideal control law of a nonlinear system and the adaptive adjusting law was adapted to assure the excellent robust stability and rejecting disturbance. Based on the Lyapunov stability theory, the global stability analysis showed that the states and tracking errors of the system are uniformly bounded. The proposed method was applied to the BTT missile, and the simulation results demonstrated the effectiveness of the proposed method.
