Motor speed control occupies a crucial position in the motion control system,
the design of the motor speed control for the study; in the basic PID control algorithm,
STM32F103 microcontroller core, by the PID control algorithm generates a PWM
pulse to achieve DC speed control. At the same time the use of photoelectric sensors to
convert the motor speed to pulse frequency feedback to the microcontroller to achieve
closed-loop speed control, to speed static error adjustment purposes. Mining 320 ×
240TFTLCD monitor as a display unit in the system, through four key settings P, I, D,
V four parameters and reversing control through the interface switching mode, start
to understand the current state of the motor and the system through the display unit
CPU temperature. The system control and high precision, has a strong anti-jamming
capability.
