In response to the problems existing in traditional servo control algorithms,a motor motion control system based on ZYNQ is developed in this paper.Due to the feedback of position data being an indispensable component of motor motion control,this paper mainly introduces the design of the photoelectric encoder data acquisition module,including the hardware circuit design and software logic circuit design of absolute encoder and incremental encoder.Through the double closed-loop test,it was verified that the designed motor motion control system has better control effect.
