For civil aircraft, the cabin pressure is kept in target range through adjusting outflow valve aperture. The actuator of the outflow valve can be driven by a brushless DC motor (BLDC) in manual mode. Since the command of the outflow valve is frequently switched between opening and closing, the BLDC operates with a “forward-reverse” cycle of rotational speed and requires frequent braking during the direction change. In order to improve the speed response of BLDC, this paper focuses on the control process of BLDC reverse braking and feed-back braking. Firstly, a BLDC speed regulation system with dual-closed-loop “speed-voltage” control was designed to achieve an ideal speed-up process by simulating the forward and reverse switching of the target speed. Then control model of the driving circuit was designed according to the BLDC braking principle, and the effects of two different braking methods were compared. Finally, a reasonable braking strategy was proposed in combination with the working environment of outflow valve.
