The trajectory tracking control precision of the ball and plate system is not high under the unknown disturbance condition. A backstepping control method is studied based on a command filter. Firstly, the ball and plate system model is established, and a second-order command filter is introduced to filter out the noise disturbance of ball position and velocity state variables. Secondly, the error backstepping controller is designed by gradually selecting the Lyapunov function. Overcome the system's external disturbance and realize the input signal progressive tracking control. Finally, the closed-loop system stability is proved by Lyapunov theory. The simulation results show that the controller can effectively suppress the system disturbance and accurately complete the trajectory tracking task.
