In order to improve the stability accuracy and anti-interference ability of the photoelectric stabilization platform under the application of Linear Active Disturbance Rejection Controller(LADRC), a Variable-domain Fuzzy Active Disturbance Rejection Control (VFADRC) method is proposed.In the case of unknown system models, a fuzzy controller that does not rely on model information is introduced into the design of LADRC.The variable factor function is used to implement variable-domain design.The VFADRC is compared with the LADRC and Model-based Active Disturbance Rejection Controller (MLADRC) methods.The simulation results show that: The designed VFADRC has the advantages of short adjustment time and small overshoot;and 2) The anti-disturbance performance is improved greatly, which can effectively improve the interference suppression capability of the photoelectric stable platform.
