Design and Implementation of Servo Motor Speed Control System Based on STM32

A speed control servo system based on STM32 is designed in order to realize the rapid, accurate, smooth speed control of rotary table. the system uses embedded microprocessor STM32F103 as the core, using the absolute encoder as the position sensor.The system achieved control of motor speed by PWM (pulse width modulation).Speed and current double loops control is used,and the expert PID control is used as the control algorithm. Through the analysis of the experimental results can be seen that the system has good stability, and the static and dynamic indicators meet the design accuracy.This design basically has reached the requirement of the servo motor speed control system.
