Design of Motor Speed Controller Based on FPGA

Abstract In the field of modern industrial automation, the accuracy and stability of motor speed control technology are essential to ensure production efficiency and product quality. The purpose of this research is to design and implement an FPGA motor speed controller based on a PID control algorithm to meet the needs of high-precision motor control. This design analyzes the principle of the PID control algorithm, including the function of proportion, integral, and differential three links and their adjustment methods. By optimizing the parameters of the PID controller, the high precision control of motor speed is realized. In the design process, this study elaborated on the FPGA implementation of PID controller-specific flow and key technology. The results show that the controller can quickly respond to the change in motor speed and output the corresponding PWM signal to adjust the motor speed.
