In order to improving the response speed and accuracy of the electro-hydraulic servo control system, the angular position test technique was investigated into the closed-loop control of the electro-mechanical converter, in-creased the stepper motor position signal as control parameter, and position closed-loop control was realized. On the basis of introducing AS5045 internal structure and its output models, this paper presents TMS320F2812 DSP as main control device and AS5045 as position feedback of electro-mechanical converter's structure. It was detailedly introduced the operating mode between TMS320F2812 and AS5045 which was based on SPI output mode, studied the position closed-loop and PID control strategy, proceeding software and hardware design and test, achieving the stepper motor's position feedback and closed loop control.
