By changing the gate voltage, one can adjust the profile and position of the static potential soliton and then have an effective control of charge solitons.
通过调节门电压可以较好地控制静电势孤子的形状及其位置，从而达到对电荷孤子的有效控制。

Thus, sensorless control strategy which only according the sampling of the current and voltage to estimate the rotor position and speed by specific methods will be widely applied.
Another kind of the voltagecontrol mode, through the high and low voltage on motor speed control, motor feedback signal through the drive to the numerical control system feedback position control.
