N2 - Aiming at the problem that the electromechanical actuator system needs to track the target without error within a finite time, fuzzy sliding mode control has been studied. Aiming at the problems of conventional fuzzy sliding mode control, such as: Low precision, low dynamic quality of system, obvious chattering phenomenon and so on, the disturbance observer is introduced to estimate the uncertainty of electromechanical actuator and combine it with conventional fuzzy sliding mode control, then a fuzzy sliding mode control method based on disturbance observer is proposed. Firstly, we build the model of the sliding mode control system of the electromechanical actuator, then design the controller and verify the stability of the system. Finally, we carried out some experiments by MATLAB and Simulink, the results indicate that the fuzzy sliding mode controller based on disturbance observer can decrease the tracking error and the response time, movement accuracy and the resistance to disturbance of the system can be improved, the system has a good performance in tracking, which has a great value to the control of electromechanical actuator.
