Open publisher page 1 citations

Abstract

According to the operation characteristic of BLDCM,an independent 4 axes position servo system actuator of brushless DC motor based on FPGA hardcore was presented in this paper.Designed all function modules and NIOS soft CPU by VHDL,and the BLDCM control algorithm with feed-forward,current,speed and position three-closed loops by C.The volume of controller is small,and it shows high reliability and flexibility,also a full-digital control can be procured.The experiment results show the advantage of BLDCM actuator FPGA-based full-digital controller.
