The current aircraft permanent magnet synchronous motor control technology has large current interference and poor motor robustness, and there is a problem that the control speed is slow. Based on this, a new aircraft permanent magnet synchronous motor speed control technology based on fractional order PIαDβ is proposed. The input current and output current of the permanent magnet synchronous motor of the aircraft are anti-interference processed by the proportional integral of fractional order PIαDβ. PIαDβ integration technology can improve the anti-interference of the control system. In the same open-loop gain environment, the controller is used to improve the robustness of the motor. The differential speed of the fractional-order PIαDβ is used to control the rotational speed of the permanent magnet synchronous motor. In order to detect the control technology effect, the contrast experiment is set up. The results show that the speed control technology of the aircraft permanent magnet synchronous motor based on the fractional order PIαDβ is based on the fractional order PIαDβ, and the relevant matching step control is selected to select the best matching control mode. The aircraft permanent magnet synchronous motor can work more efficiently and the control speed is increased by 12.81%.
