N2 - Since the aircraft has the special requirements for the electromechanical actuator (EMA), the electrical servo control system using brushless DC (BLDC) motor is designed to fulfill these requirements in this paper. An angular position detecting method of helm is proposed to overcome the electromagnetic interference from the PWM inverter. This method combines motor's discrete Hall sensors signal with a potentiometer signal to determine the position information. In order to realize the fast response of the system, and eliminate the DC-Link voltage pumping-up phenomenon, an improved reverse braking method is applied, which can realize the torque control. In order to improve the system response, the current controller and the position controller is applied. Experimental results show that the tracking performance of the proposed control system can fulfill the requirements.
