The design of backstepping controller based on BTT missile

The performance of the controller is the key to ensure that the missile has a good stability and controllability in the guidance of flight. Without considering the coupling among channels, the three-channel missile body mathematical model of BTT-90 missile is established, and the model is based on BTT control technology. The Backstepping controller is designed and BTT-90 missile closed loop control system is constructed respectively. The result of simulation analysis shows that the control system can track the command signal rapidly, and has good dynamic and steady-state characteristics.
