Abstract
In order to achieve a simple and efficient brushless DC(BLDC)motor drive system of the brushless DC motor,a simple model of FPGA is presented based on the digital pulse width modulation(PWM)controller,model and control algorithm. The controller will take BLDC motor flux distribution of the ladder as a digital system,low power and the alternate use of high-powered speed adjustment,it is easy to realize the design and implement. In ad⁃dition,a current sensor design is proposed only by using the DC link to reduce the cost and the complexity of hard⁃ware. And through the simulation experiment of the proposed control method was verified,the results show that the maximum error of the proposed method is decreased below 5%. Therefore,the control technology is very suitable for applications that don't require high accuracy.关键词
