Abstract: The electromechanical actuation system composed of permanent magnet synchronous motor (PMSM) is widely used in aviation equipment. The torque response, efficiency, and steady-state control accuracy of the motor directly affect the performance of aviation equipment. However, there are disturbances such as motor parameter perturbation and load fluctuation in aviation electromechanical actuation. To suppress the influence of disturbances on the dynamic and steady-state performance of the drive system, active disturbance rejection control (ADRC) has become a research hotspot. Based on the background of the aviation electro-mechanical actuator system, the multi-source disturbance in the electro-mechanical system is sorted out. The research results of ADRC in PMSM high-performance servo in recent years are summarized. The research status of strong anti-disturbance feedback control law, current loop anti-disturbance control strategy, disturbance observer of speed and position loops are reviewed. Finally, the research difficulties and challenges of electro-mechanical actuators in the aviation field are summarized, and the development trend of ADRC-based PMSM servo control technology is prospected.
