Abstract

According to the demand of high integration of servo motor control system, a method of resolver-to-digital conversion (RDC) based on FPGA is proposed. This method adopts the technology of synchronous excitation and peak sampling, which can realize the peak sampling of sine signal and cosine signal of resolver through low-speed and high-precision ADC. The method realizes high-precision angle-to-digital conversion by CORDIC algorithm and closed-loop tracking algorithm. Based on the principle of this method, a improved servo motor controller is developed and applied to the servo system. The comparison test between the improved servo motor controller and the traditional controller is carried out. The test results show that the resolver-to-digital conversion method is correct and feasible. The improved controller developed based on this method has normal function and better dynamic characteristics.
