电液比例往复运动的定位控制方法

Positioning control method for electrohydraulic propor-tional reciprocating motion

本文针对只需在有限点准确定位的往复运动系统,介绍了几种利用比例速度控制实现的往复运动定位控制的方法和原理。并较详细地介绍了行程末端位置反馈定位的电控原理和设计思想。

This paper deals with the electrohydraulic proportional reciprocating motion which has only a few positions that need accurately positioning. Some positioning methods and principle of reciprocating movement by means of electrohydraulic proportional speed control are discussed. Also the principle and design method of the position feedback at the end of stroke are introduced in more detail.
