在机械加工、机械操作和其它许多应用中,经常会出现使用比例控制还是伺服控制的问题。本文由瑞士凡佛鲁(Wardfluh)和佛鲁提根(Frutigen)公司提供,讨论了选择时应考虑的问题和应评价的数据,同时简要介绍了该公司生产的控制阀件及其典型用途。一般地说,除非要求闭环进给控制或高频响应,比例技术在工业和车辆、装卸和机器人方面的应用中占有一定的位置。 In machining, mechanical operation and many other applications, the question of whether to use proportional control or servo control often arises. This article was provided by Wardfluh and Frutigen in Switzerland and discusses the issues to be considered and the data to be evaluated, as well as a brief overview of the company’s control valves and their typical uses. In general, proportional technology occupies a certain place in industrial and vehicle applications, handling and robotics unless closed loop feed control or high frequency response is required.
