zero plane

Closed-loop system transfer function of inner current loop has the right half plane zero and close from the imaginary axis, so that the control system Q value is larger and the setting time is longer. It lags the system harmonic compensation time.

系统电流内环闭环传递函数中存在右半平面零点且距虚轴较近，这样造成控制系统Q值较大、调节时间加长、系统谐波补偿滞后。
