The principle of the method of pulse feedback of systematic variable is explicated. On this basis, algorithm procedure of the new method is demonstrated, and its validity is theoretically proved.

阐述了系统变量脉冲反馈控制法的基本原理和新方法的算法过程，并从理论上对该方法的有效性进行了严格论证。

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。
