Abstract
An improved active disturbance rejection controller (ADRC) based on particle swarm optimization (PSO) is proposed to solve the problems of control accuracy, response speed and parameter tuning in the current dynamic communication antenna servo system. Firstly, the models of antenna servo system and ADRC controller are established; Secondly, the structure of ADRC controller is simplified to reduce the parameters to be set in parameter setting; The particle swarm optimization algorithm is used to further adjust the relevant parameters in the original parameter setting method, and finally realize the control of the moving through antenna servo system. The simulation results show that compared with the control effect of traditional PID controller, the improved ADRC controller has the characteristics of small overshoot, fast response, high precision and strong anti-interference ability, and has good reliability and robustness.
