Abstract

The disturbance is an important factor that affects the stability control of the photoelectric tracking servo system. In order to make the system be able to track the target stably and accurately, it must realize the disturbance isolation. In this paper, the coordinate transformation technology is used to conduct the real-time compensation for attitude angle caused by ship swaying and the fiber optic gyro feedback control is applied to achieve the effect of the line of sight (LOS) stabilization. Compared to the traditional PID controller with weaker anti-disturbance ability, the second order linear active disturbance rejection control (LADRC) is proposed and used for speed loop to improve the anti-disturbance ability. The simulation results show that the system where the speed loop uses LADRC has better control effect and stronger anti-interference ability.
