Motor Control Application Based on STM32 and PID Control Theory

Abstract:

This paper introduces a motor control application. In terms of hardware, we design and build the motor control board based on STM32 microcontroller (MCU). In software part, the code loaded in the MCU is designed to apply a feedback control on the motor based on proportional-integral- derivative (PID) control theory and the three loops control of motor. We have achieved the angular displacement and speed control of the DC brushed motor in this application. Thanks to the current loop control of the motor, the controlling performance less sensitive to the external disturbance and the robustness is better compared with the motor controller in current market like LM629. Besides, the maximum current passing through the motor can be set by user in the program, which makes this motor control board more stable and durable.
