The motor speed feedback signal measured by the photoelectric encoder is fed back to the single chip microcomputer. The setting speed of the motor is obtained by the ZLG7289 module and transmitted to the microcontroller through SPI communication. The single-chip microcomputer system gets the deviation according to the actual speed subtracted from the given speed and feedback, and gets the control quantity through the control algorithm. The microcontroller output the control volume in the form of PWM, and drive the DC motor through L298 power amplification. ZLG7289 module is mainly used to display the actual speed and given speed of the current DC motor, and let the user input the set speed through the keyboard.
