Abstract:

Aiming at the dynamic coupling and nonlinear control of hypersonic guided projectile, a feedback linearized terminal sliding mode controller is designed. Firstly, the nonlinear control model is established by considering the simplicity of control system design and the strong nonlinear characteristics of the hypersonic guided projectile. Then the dynamic coupling problem in the model, the feedback linearization is carried out according to the theory of differential geometry to realize the decoupling of pitch channel and yaw channel. Finally, the terminal sliding mode controller is designed for the two channels respectively, and the controller converges in finite time. The simulation results show that the designed controller can track the command signal quickly and stably, and still has good robustness in the case of external interference and parameter perturbation.

Key words: hypersonic guided projectile, nonlinear, feedback linearization, terminal sliding mode
