An Adaptive Fuzzy Variable Structure Controller for Bank-to-Turn Missile

This paper address the control problem for the bank-to-turn (BTT) missile, which is a complicated nonlinear system. BTT autopilot is not simple, mainly due to the nonlinear and coupled character of system equations, the lack of a precise model for the missile dynamics and parameters, as well as the appearance of internal and external perturbations. The proposed methodology is an approach included in the control areas of nonlinear feedback linearization, fuzzy control and uncertainties consideration. It is based on the fusion of a sliding mode controller and fuzzy basis function networks (FBFN), including the advantages of both systems. The main advantage of this methodology is that it relaxes the required knowledge of vehicle model. The experimental results demonstrate the good performance of the proposed controller, within the constraints of the sensorial system and the uncertainty of the theoretical models.
