In order to accurately control the movement of the cargo door of the aircraft and realize the quick opening or closing on the premise of satisfying the slip amount, a motion control strategy based on the electro-mechanical actuator (EMA) is designed.

Firstly, the mathematical models of the controlled permanent magnet synchronous motor (PMSM) and the load platform used to simulate the mechanical characteristics of the cargo door are established, and the calculation formulas of the load and the moment of inertia are obtained, which are used for subsequent simulation verification.

Secondly, a speed planning strategy is designed, which uses the current open position to calculate the reference speed in real time, and through the speed closed-loop vector control, the electromechanical actuation system can quickly and accurately realize the opening and closing actions in all positions. The effectiveness of the strategy is verified by simulation.

Finally, the control strategy is verified by the experiment on the electro-mechanical actuator based on Field Programmable Gate Array (FPGA), and the actuator is loaded by the load platform.
