基于单片机的步进电机控制系统设计研究-临沂大学毕业论文

Design of the Control System of Step-Motor Based on Single Chip Microcomputer The step motor, a widely used component in various fields such as office automation equipment like printers and control devices, is favored for its simplicity, cost-effectiveness, and feasibility in open-loop systems. This paper introduces a design of a step motor system based on a single chip microcomputer. Programs for the motor's forward rotation, reverse rotation, speed control, and stopping are written in assembly language and C language. These programs are executed through the single chip microcomputer, the motor driver chip ULN2001, and corresponding buttons. Additionally, the working status of the step motor is displayed on an LCD screen. This paper elaborates on the principles of the step motor and single chip microcomputer, the hardware circuit of the system, and the composition of the programs. The soft and hardware components are debugged, and the problems encountered during the debugging process are discussed along with their solutions. The design features a clear train of thought, high reliability, and strong stability, and the desired functions are achieved through successful debugging.
