The servo control system combines position loop, speed loop, currentloop with algorithm of space vector pulse width modulation(SVPWM).
系统采用位置、速度和电流环三环控制,并结合空间矢量脉宽调制(SVPWM)算法。

Finally, the indirect vector control system is made as the research target and double close loop control systems which contain synchronous current inside loop and speed outside loop are introduced.
