Decoupling Controller Design for BTT Missile With Coupled Channels Based on Sliding Mode and Neural Network

Aiming at the serious coupled channels control problem in BTT missile, this paper adopts theories of sliding mode and neural network to design missile controller. Firstly, sliding mode control and neural network are introduced, and the joint equation of states for pitch and yaw channels of BTT missile is established. Secondly, the coupling factors are estimated by the linear extended states observer for decoupling and the control laws of coupled channels are designed. Thirdly, in order to decrease the chattering of sliding mode control, the gain term of sliding mode would be adjusted by RBF neural network online. Finally, the performance and robustness of the designed controller are verified by simulation.
