At the same time using Holzer sensors will be converted into pulse frequency motor speed feedback to the MCU, realize the speed closed-loop control, to achieve speed detection.
同时利用霍尔传感器将电机速度转换成脉冲频率反馈到单片机中，实现转速闭环控制，达到转速检测目的。
The high frequency gain of the regulator is limited to suppress the high frequency oscillation of the control signal while assigning the closed-loop poles.
在配置闭环极点的同时，对调节器的高频增益加以限制，以减弱控制信号的高频振荡。
By adjustment to control signal, systems might realize variable voltage, variable frequency, steady voltage, steady frequency closed loop control.
