The article firstly provides the composition and principle diagram of the antenna tracking control system, and the closed-loop workflow of the system is described. Secondly, in the process of antenna tracking target, the error between the target output by the tracking receiver and the center angle of the antenna beam is affected by the random error component. The Kalman filtering algorithm is used to filter the real-time angle position data obtained. Thirdly, the antenna tracking control system is modeled, the system dynamics model is given, and the dual motor anti-backlash design scheme is simulated. Finally, the reliability of the system is verified by the flight test.
