Design and Implementation of Brushless DC Motor Control Scheme Based on RT-Thread Operating System

The brushless DC motor is widely used in the market due to its excellent performance, and its speed adjustment often requires a controller to control. The real-time nature of the control algorithm and calculation feedback is the core of the system. In response to the requirements of the brushless DC motor system for the stability and response speed in the speed regulation process, a speed loop control scheme based on the RTThread embedded real-time operating system was designed on the STM32F407 platform, and the Hall sensor was used to realize the PID closed-loop control of the speed loop. The scheme has the advantages of high stability, fast response speed, and small overshoot.
