基于DSP的永磁同步电机速度与位置计算方法

现代数控系统,对控制精度要求越来越高。在这个要求的基础上,对电机速度和位置的控制就成了首要的问题。为了更好地提高对精度的控制,以达到系统高性能的要求,文章以TMS320LF2812 DSP芯片为核心控制芯片,设计一种基于PMSM速度与位置计算方法。通过这种方法建立PMSM矢量控制系统,从而提高系统性能。

The modern numerical control system,to controls the precision request to be more and more high.In this request foundation,has become the most important question to the electrical machinery speed and the position control.For a better enhancement to the precision the control,achieves the system high performance of the request.The article take TMS320LF2812 the DSP chip as the core control chip,designs one kind based on the PMSM coordinate system layout count method.Establishes the PMSM vector control system through this method.Thus enhances the overall system the performance.
