这个例子展示了如何使用一个闭环磁场定向控制（FOC）算法来调节转速和转矩的三相永磁同步电机（PMSM）。本例使用的C28x周边区块和C28x DMC库模块的嵌入式编码器支持包德克萨斯仪器C2000处理器。(This example shows how to use a closed loop magnetic field orientation control (FOC) algorithm to adjust the speed and torque of a three-phase permanent magnet synchronous motor (PMSM). The embedded encoder of the C28x peripheral block and the C28x DMC library module used in this example supports the package Texas instrument C2000 processor.)
