The invention discloses a control system of automatic revolving door. The control system, which adopts a closed-loop control structure formed by location, speed and current, comprises an input module, a closed loop and speed controller of door leaf, a speed governor, a first current regulator, a second current regulator, a reverse transformation module, a space vector pulse width modulator, a motor driven module, a current sampling module, a signal conversion module, a motor, and a module for calculation of pole location and speed of the motor; the control flow is: first, a setting signal is provided to the closed-loop control formed by location, speed, and current; second, the output signal of the closed-loop control goes through the space vector pulse width modulator and reverse transformation module and forms the three-phase AC signal of the drive motor; finally, terminal voltage and phase current of the motor are acquired by the sampling module and processed by the signal conversion module to be the feedback signal of the closed-loop control structure. The control system of automatic revolving door is energy saving and environmental friendly, low in noise, reliable in operation, easy to install and debug, and has the anti-clip function.
