Design of Servo Control System for Stepper Motor Based on MCU and Infrared Remote Control

Abstract:

A four-phase stepper motor servo control system is designed by a master chip STC89C52 and driver chip ULN2003A. Operation in four modes of stepper motor is achieved by keys. Speed control of stepper motor is achieved by A/D conversion chip TLC1549 and adjustable potentiometer. Dynamic display circuit of digital tube is designed by a shift register 74LS164. At the same time, operating in four modes, speed control and turning its particular angle of stepper motor are achieved by the infrared receiver HS0038. The experimental result shows that the control system is reliable, and it has some practical value.
