本文介绍了把单片机用于一种新型的数字阀所组成的液压系统,它配以精度高的光栅尺作为检测元件,省去了一般数字式液压控制系统的A/D、D/A接口,因此它结构简单,造价低、便于推广。可快速、无振荡抵达控制目标,特别适用于机床等响应速度不高的工业控制。 This paper introduces the use of a single-chip digital valve consisting of a hydraulic system, which coupled with high-precision grating as a detection element, eliminating the general digital hydraulic control system A / D, D / A interface, Therefore, it is simple in structure, low in cost and easy to popularize. It can reach the control target quickly and without oscillation, especially suitable for industrial control such as machine tools with low response speed.
