Dynamic Inversion controller design for BTT Missile Based on Sliding Mode control

Aiming at nonlinear BBT control problem with uncertainty and serious coupled, this paper adopts dynamic inversion theory and sliding mode theory. Firstly, the control system was divided into slow loop and fast loop based on the singular value perturbation theory. Then dynamic inversion control method is applied for both two loops. The sliding mode control is adopted to overcome the inverse error caused by inaccuracy of model and parameter perturbation. The control law of slow loop is given and stability of close loop system is proved. Finally, the performance and robustness of the designed controller are verified by simulation.
