Simulation of BTT Missile Based on Variable Structure Adaptive Control

A novel automatic pilot control law based on variable structure adaptive control,which is independent of the system's precise math model,is adopted to solve the uncertainty of BTT missile aerodynamic parameters.The simulation software Matlab is adopted to simulate BTT missile's roll,yaw,pitch channels and the closed loop system.Then necessary improvement is performed for solving the problems existing in the control system.The control law adopted in this thesis settles the problems that missile mathematic model can't be obtained exactly and parameters change,and the coupling between channels is also overcome.The algorithm is simple and can be simulated easily.
