Abstract: Based on FPGA-field Programmable gate array,designed and implemented speed control of Brushless DC Motor(BLDCM).Designed PWM-pulse width modulation with hardware programming language-Verilog HDL.In order to design digital PID,Xilinx IP core was used.By detecting the three-phase signals of BLDCM Halls,to achieve the three-phase six-state run.The entire system only has a single FPGA chip,fully utilizes the powerful logic FPGA computing power,reducing overall system cost.
