Closed-loop control device and method of brush motor based on superposition theorem

The invention provides a closed-loop control device and method for a brush motor based on the superposition theorem, and relates to the technical field of brush motor control, and the closed-loop control device comprises a micro-control unit MCU and a DC power supply. The MCU is used for acquiring real-time state parameters, collected by the sensor, of the brush motor driving equipment, performing closed-loop control on the real-time state parameters and target state parameters, and outputting analog signal voltage to the direct-current power supply; and the direct current power supply is used for adjusting the analog signal voltage and the external input voltage and outputting working voltage to the brush motor. According to the closed-loop control device, continuous speed regulation of the brush motor can be realized, and the closed-loop control device has relatively high anti-interference capability. 本申请提供了一种基于叠加定理的有刷电机的闭环控制装置及方法，涉及有刷电机控制技术领域，其中的闭环控制装置包括：微控制单元MCU和直流电源；所述微控制单元MCU，用于获取传感器采集的有刷电机驱动设备的实时状态参数，对
