| Abstract: | To improve the stepper motor stall, out of step, over step and other issues, increase step accuracy, and made it be located quickly and accurately, proposed a stepping motor control system based on the STM32F4 microcontroller design. To control the motor speed can change the prescaler of timer which generated PWM, straight line stepped acceleration and deceleration algorithm speed; Using DMA mode control motor pulse number, to achieve precise position control. Experiments and practical application shows, stepped trapezoidal landing speed algorithms and DMA mode position control algorithm can meet the general requirements, the system error is under ±0.01 degrees. High precision, reliable performance, and expandability made it has a higher value. |
