摘  要
变频调速以其优异的调速和启制动性能,高效率、高功率因数和节能效果,广泛的适用范围及其他许多优点而被国内外公认为最有发展前途的调速方式,是当今节能、改善工艺流程以提高产品质量和改善环境,推动技术进步的一种主要手段。
可编程程序控制器(简称PLC)以其功能完备、组合灵活、编程方便、同时可靠性高、开发周期短而广泛应用于工业生产与控制的各个领域中。因此，以PLC作为控制系统，大大提高了对交流电机变频调速的稳定性、可靠性、准确性。同时，由触摸屏作为控制系统的人机界面，对实时数据、系统动作等进行监控和调整，更加直观和易操作。
本文设计了基于变频调速的疲劳实验装置，并用三维软件SolidWorks画出该系统装置的三维图；由三凌PLC编辑程序梯形图，以实现对系统的各种运动，如连续运动，往复运动，正反转等；最终由EasyBuilder做出触摸屏控制的各种人机界面。

Abstract
Frequency Control its excellent speed and start-stop performance, high efficiency, high power factor and energy-saving effect, a broad scope of application and many other advantages at home and abroad were recognized as the most promising of the governor, is the energy-saving, improve the process to improve product quality and improving the environment, promote technological progress as a major means.                
Programmable process controller (PLC) for its complete functions, the combination of flexible, easy programming, high reliability, short and exploitation cycles widely used in industrial production and control in all areas. So, using the PLC as control system, it thereby greatly increases the stability, reliability and accuracy of the frequency control of the AC motor. At the same time, the touch-screen control system, as the man-machine interfaces, the real-time data, the system moves to carry out monitoring and adjustment, more intuitive and easy operation.     This paper was designed based on Frequency Control of fatigue experimental device and used 3D SolidWorks software to draw installation of the system of three-dimensional map; Compiled ladder diagram by Mitsubishi PLC to achieve the system's various campaigns, such as continuous movement, reciprocating movement, Positive and; Finally made the touch-screen control of man-machine interface by the EasyBuilder.

Keywords: frequency control; PLC; touch-screen; reciprocating movement.
