摘要	In order to improve the ability of anti-disturbance of the servo control system for photoelectric platform, an improved velocity loop based on ADRC method was presented. Firstly, the analyses of boresight stability loop of the photoelectric platform were conducted to simplified its mathematical model. Then the general disturbance was introduced by analyzing the disturbance mechanism in servo control system. Secondly, a new controller based on a reduced-order ESO was designed, and was applied to the improved velocity loop, which took real-time observation on the general disturbance and compensated the disturbance linearly. Finally, a contrastive experiment was conducted between PI controller and ADRC controller by using a vehicle-borne photoelectric platform as control object. The experimental results showed that the speed of step signal response of ADRC controller was faster than that of PI controller. The overshoot amplitude was only 26.98% of that in PI controller. When the frequency of 2.5 Hz sinusoidal disturbance was used by swing table, the system steady-state error amplitude was only 9.76% of that in PI controller. Within the scope of the system model parameters changed plus or minus by 15%, the ADRC controller still achieved excellent anti-disturbance capacity, which showed strong robustness and met the performance requirements for vehicle photoelectric platform. It is very practical in improving the capacity of disturbance resistance for photoelectric platform. 2018, Science Press. All right reserved.
