Design of Attitude Controller for Hyper Velocity Projectile Based on Active Disturbance Rejection Control

Aiming at the problems of cross-coupling and uncertain disturbance in the attitude control design of hyper velocity projectile configured with a pair of steering gears, an attitude decoupling controller based on active disturbance rejection technology is designed. The controller is simple in structure and less dependent on mathematical models. The effectiveness of the controller is verified by numerical simulation. The results show that the designed attitude controller can effectively realize the decoupling between the three channels, track the pitch and roll commands quickly and accurately, and has good anti-interference ability. In addition, the controller is not sensitive to the perturbation of model parameters in an extensive range and has strong robustness.
