Abstract

Aiming at the problem of insufficient disturbance suppression ability of photoelectric stabilized platform system under traditional ADRC, an Active Disturbance Ｒejection Controller based on variable gain differentiator(VGD-ADRC) is proposed. In order to alleviate the contradiction between observation accuracy and noise sensitivity, a variable gain differentiator is used to replace the linear extended state observer. At the same time, the tracking error feedforward and disturbance feedback are separated to reduce platform overshoot. By comparing the simulation of VGD-ADRC and traditional LADRC, the results show that the VGD-ADRC can eliminate the overshoot of the system, improve the noise suppression ability and enhance tracking accuracy of the photoelectric stabilization platform.
