Design and Simulation of Adaptive Backstepping Control Law for BTT Missile

In order to solve the problems of multiple variables and strong coupling in BTT(bank-to-turn) missile control,a backstepping algorithm suitable for the BTT missile autopilot controller was proposed.Based on the peculiarity of BTT missile,the nonlinear model of missile was built up.Then,the missile model was translated into a feedback block model to realize the backstepping design.A special nonlinear synthetical backstepping method was applied in design of the control law for BTT missile,which added neural networks to solve the uncertainties problems,and the adaptive tuning rules were derived using the Lyapunov stability theorem.This method can implement the decoupling design of controller and track the command signals well.Simulation was made to demonstrate the effectiveness of the proposed method.
