基于DSP的无刷直流电机无传感器控制系统设计

Sensorless controlled brushless DC motor control system based on DSP

针对以往无刷直流电动机反电势法无传感器控制系统存在的一些问题，设计了一种基于数字信号处理器（ＤＳＰ）的无刷直流电动机无传感器控制系统，详细介绍了系统的控制方案。实验结果表明，系统的硬件和软件设计合理，具有良好的调速性能。

Aiming at some problems existing in former FMF-method sensorless control system for brushless DC motor, a novel control system based on DSP is designed and the system control scheme is discussed in detail. Experimental results show that the hardware and software of system are reasonable and good speed adjusting performance can be achieved.
