摘　　要：为了能够准确地获得无刷无位置直流电动机转子位置的换相信号,采用基于虚拟中性点电位的三次谐波检测法,并对此检测法进行仿真和实验验证,设计出了以TMS320F2812为核心的全数字调速系统,给出了硬件电路的设计,并对九点五态控制器做出了数学解释。实验结果表明:该系统具有较强的鲁棒性和抗干扰能力,且超调量小,响应时间快。In order to obtain the accurate location of a brushless DC motor for the rotor position, the paper adopts virtual neutral point potential-based three harmonic detection method with simulation and experimental verification. A TMS320F2812-based all-digital speed control system is designed, its hardware circuit is introduced, and the nine point five state controller is explained. The results show that the system is of robust and anti-jamming capabilities, small overshoot, and fast response time.
