摘　　要：设计了一种基于数字信号处理器(DSP)的无位置传感器无刷直流电机的控制系统。介绍了反电动势过零位置检测的原理及实现方法,并采用了数字式转速、电流双闭环控制。整套系统结构简单,采用软件实现了大部分控制功能。试验结果证明了设计方案的可行性。One kind of sensorless control system for brushless DC motor based on DSP was introduced and the principle of back-EMF zero-crossing detection and realization method was discussed in detail. It adopted the digital speed and current closed-loop control strategy. The system adopted more reasonable software structure instead of the former complicated hardware circuit. The experiment results proved the possibility of this project.
