Improved Active Disturbance Rejection Control of optoelectronic stabilized platform Based on Reduced-order Extended State Observer
2021
In order to improve the anti-disturbance ability and dynamic response characteristics of the optoelectronic stabilized platform, an improved linear active disturbance rejection control (ADRC) algorithm is proposed. The algorithm adopts reduced-order extended state observer (RESO) to realize fast tracking and estimating disturbances, which improves the restraining rapidity of disturbances. The Variable Speed Integral Proportional Integral (VSIPI) algorithm is introduced to solve the contradiction between transition speed and response overshoot, so as to obtain faster response speed and lower overshoot. The simulation results show that the algorithm has stronger anti-interference ability and robustness than the traditional PI.
