摘要

In order to enhance the stability of the metro platform screen doors (PSD), and to enable PSD to smoothly complete the process of closing and opening, this article proposed a control method based on the double closed loop speed regulating system of brushless direct-current (DC) motor. By means of double closed loop PI control of the motor speed loop and current loop, precise and stable control of brushless DC motor was realized, and the velocity curve of PSD was obtained, which could make PSD run smoothly. Finally, through the experimental analysis of the control system, the data curve satisfying the requirement of the control curve was acquired, which verified the reliability of the double closed-loop control of the brushless DC motor in the PSD control system.
