Abstract

Abstract

In order to improve the tracking stability and accuracy of photoelectric tracking control system, the control method of photoelectric tracking servo system is studied in this paper. Firstly, in order to meet the requirements of system function and performance index, the structure of the servo turntable is designed. Then, the linear Active Disturbance Rejection Control (ADRC) algorithm is designed, tracking differentiator and the linear extended state observer and state error feedback control law are obtained. Then, the model of tracking servo system based on ADRC algorithm is established with Matlab/Simulink, in which the position loop and speed loop adopt the second-order ADRC strategy, and the current loop adopts the PI control strategy. The simulation results show that zero overshoots can be realized during positioning tracking, and the fastest response speed can be achieved. When sudden disturbance is added, the maximum value of dynamic landing is 3%, and the sinusoidal tracking error can reach 0.02°, demonstrating that the photoelectric tracking control system based on ADRC algorithm has good results in fast response, steady-state accuracy and anti-interference performance.
