【Abstract】 The problem of nonlinear decoupling control is studied by the differential geometry control theory for bank to turn(BTT) missile. Firstly,the sufficient and necessary condition of decoupling of nonlinear system is given. Secondly, nonlinear decoupling control law of BTT missile is designed. Finally, the control system simulation algorithm of BTT missile is developed by the nonlinear decoupling control law, and the simulation results show that designed nonlinear decoupling control law can restrain crisscross coupling among roll, pitch and yaw channel, and track control command effectively.更多还原
