液压伺服系统依控制讯号的不同分电液、气液和机械液压伺服系统三种。液压伺服跑偏控制一文,介绍了气液伺服跑偏控制系统的设计;本文对西德“EMG”电液伺服跑偏控制系统作一分析。前者是一设计实例,着重介绍设计程序及方法;本文是从另一个角度,即如何分析一个已有系统的调节品质;如果不能满足要求,则如何加以调整和改进。本文可算是前文的续篇,供设计和现场调整参考。
Hydraulic servo system in accordance with the different control signal sub-liquid, gas and liquid mechanical servo system three. Hydraulic Servo Drift Control, a paper introduces the design of gas-liquid servo deviation control system. This paper analyzes the “EMG” electro-hydraulic servo deviation control system in West Germany. The former is a design example, focusing on the introduction of design procedures and methods; This article is from another perspective, that is, how to analyze the quality of an existing system of regulation; if you can not meet the requirements, how to adjust and improve. This article can be considered the sequel to the previous article for the design and on-site adjustment reference.
