单片机控制步进电机论文单片机控制交通灯论文 基于Proteus与单片机的步进电机控制设计 摘要:步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。采用AT89C52单片机内部的定时器改变CP脉冲的频率从而实现对步进电机的转速进行控制,实现了电机调速与正反转的功能,并使用EDA软件Proteus对设计进行了仿真,同时还设计了硬件电路。结果表明,使用Proteus仿真结果与硬件电路实验结果基本一致。先采用Proteus仿真,再移植到相应的硬件电路,这种方式可以减小系统开发成本和周期,具有一定的推广价值。 关键词:步进电机;单片机;调速系统;Proteus 中图分类号:TP27文献标识码:A 文章编号:1004-373X(2010)05-104-03 Design of Control System of Stepper Motor Based on Proteus and Single Chip puter YANG Hong,LI Guohui (Xi′an University of Post and munications,Xi′an,710061,China) Abstract:Stepper motor is the open-loop control device changing the electrical pulse signal into angular displacement or linear speed of stepper motor is controlled by turning the CP pulse frequency by the internal timer of AT89C52 single chip puter,and its normal-reverse function is simulation is done by the Proteus software of EDA,and the hardware circuit is also results show that the simulation results by Proteus software and the hardware experimental results are basically consiste simulation is used firstly by Proteus,and it is transplanted into the corresponding hardware way can reduce system′s developing costs and cycle,and has a certain promoting value.
