A control method of the electromechanical actuator is discussed by the actuator work theory researched. Simulation results indicate that the designed electromechanical actuator, which is driven by a brushless DC motor and is forced by the alternate loading, can ensure the accuracy of phase compensation and rotation synchronization.
