摘要
在液压伺服控制系统及控制工程中经常会遇到一些重要概念、定义及术语,可以通过实验教学加以理解,但所使用的设备、仪器数量、时间及复杂程度都将是惊人的,在教学时间内几乎不可能完成.为此,介绍了由伺服阀控制对称液压缸和位移传感器构成的液压位置闭环控制系统及其工作原理,给出了该系统的频率特性及动态响应数学表达式.以VISUALBASIC为开发工具,开发出了适用于液压伺服控制系统及控制工程基础课程的教学课件.
For hydraulic servo control system and control engineering,many important concepts,definitions and items met from time to time can be understood through experiment teaching.However,the quantity of instrument,time spent and the complexity would be astonishing,which can not be completed in predetermined teaching hours.In this paper,the domination principle of the hydraulic position closed-loop system consisted of the position sensor and symmetrical hydraulic cylinder controlled by the servo valve is introduced.The mathematical models of frequency characteristics and dynamic response of the system are discussed.With Visual Basic Language,the CAI suitable for the hydraulic servo control system and the control engineering foundation is developed.
