出一种新 的SVPWM 算法。采用SPWM 中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM 周期中的占空比。-A new SVPWM algorithm. SPWM modulation used in the carrier wave, compared with the rules of sampling ideas, through the static coordinate system d

检测电机转速通过pid算法对电机PWM占空比调节使电机达到预定转速(The motor speed is detected, and the duty cycle of the motor PWM is adjusted by the PID algorithm, so that the motor reaches the desired speed)
