This sample program generates two sine waves called X and Y. It will then calculate the normalized MAGnitude and phase of the two waveforms using the following formulas: MAG = sqrt(X^2 + Y^2)/sqrt(GainX^2 + GainY^2) Phase = (long) (atan2PU(X,Y) * 360) The program will prompt the user to change the gain and frequency of the X and Y waveforms.

简介本文档介绍了如何使用dsPIC30F数字信号控制器(Digital Signal Controller,DSC)控制正弦电流来驱动具有位置传感器的永磁同步电机(Permanent MAG-net Synchronous Motor,PMSM).电机控制固件使用dsPIC30F外设,而数学运算则由DSP引擎完成。为充分利用dsPIC30F的特殊DSP运算性能,固件采用C语言编写,只有某些子程序采用汇编语言编写。应用特性·使用空间矢量调制(Space Vector Modulation,SVM)方法产生用于驱动PMSM电机各相的正弦电流·正弦电压与PMSM电机转子位置同步·四象限运行,可实现正向、反向和制动运行·基于数字比例一积分一微分(Proportional Integral Derivative,PID)控制的闭环转速控制·相位超前技术可实现更宽的调速范围·由dsPICODSC的DSP引擎实现小数数学运算
