Abstract

The photoelectric stabilized platform is used for target tracking, which keeps the visual axis of the device stable and accurately points to the target through the servo system, but it is affected by the disturbance torque, which causes the tracking performance to decline. In order to overcome the influence of disturbance torque, the disturbance observer is applied in the three-loop servo control system of the photoelectric stabilized platform to improve the tracking accuracy of the photoelectric stabilized platform. The simulation analysis of the improved servo control system shows that the tracking position error range is reduced from 0.006° to 0.001°, which proves the feasibility of the method.
