In order to further improve the imaging stability of photoelectric devices such as lidar, this paper studies the influence of the introduction of fuzzy control into the linear active disturbance rejection controller on the stability and anti-disturbance performance of lidar imaging. When the system model is unknown, the fuzzy control that also does not depend on model information is introduced into the linear active disturbance rejection control(LADRC), and the fuzzy control is used as the active disturbance rejection controller, and the LADRC is nonlinearized through the fuzzy control. Taking the photoelectric stabilization platform as the research object, the fuzzy active disturbance rejection (FADRC) is simulated and compared with the traditional design method. The simulation results show that the fuzzy active disturbance rejection proposed in this paper can effectively improve the response speed and anti-disturbance ability of the photoelectric stabilized platform. The response speed is increased by 50%, the overshoot is reduced by 67.3%, and the disturbance isolation ability is increased by 20.3%. It can greatly improve the imaging stability of lidar.
