Abstract:

In order to improve the tracking accuracy and disturbance suppression ability of fast steering mirror (FSM), a FSM closed-loop control system based on active disturbance rejection control (ADRC) is established, and the parameter setting method of ADRC is studied. Because the setting efficiency of ADRC parameters by trial and error method is low, and it is easy to fall into local optimization by particle swarm optimization (PSO), an improved PSO (IPSO) algorithm based on skip tongue line adjustment of inertia weight is proposed. Through the system simulation experiment, considering the vibration of satellite platform, ADRC and traditional proportion integration differentiation (PID) controller based on IPSO and PSO are used to control FSM respectively. The results show that when tracking high-frequency sinusoidal signals with different frequencies, the tracking accuracy of FSM controlled by ADRC based on IPSO is significantly improved compared with the other two controllers.

Key words: fast steering mirror, active disturbance rejection control (ADRC), particle swarm, inertial weight, versoria function
