讨论了一种采用DSP芯片TMS320LF2407实现无传感器永磁同步电机转子磁场定向矢量控制的方案,介绍了永磁同步电机的数学模型和矢量控制的基本原理,给出了在无位置传感器的情况下电机转子位置信号的确定方法,采用id=0的对凸极式转子磁路结构的无传感器永磁同步电动机的控制方法,说明采用高速数字信号处理器易于实现复杂的矢量控制算法,可以有效地解决电机的强耦合特性.

A solution to control a permanent magnet synchronous motor（PMSM） of sensorless using the TMS320LF2407 is discussed. A brief introduction of the mathematic model and the vector control of PMSM is presented, and the method of ascertaining the rotor position under the circumstance of speed sensorless is also mentioned. The control method of id = 0 on salient pole PMSM which is sensorless is put forward, which shows that if we use the digital signal processor we can make the complicated vector control arithmetic come true easily, and can also resolve the coupling characteristic of motor effectively.
