Predicting Response of a Proposed Hydraulic Control System Using Bond Graphs

Abstract

Dynamic response is an important criterion of quality for many hydraulic control systems. It is suggested that power flow modeling procedures, and in particular the recent development of power bond graph techniques, provide the designer-analyst of hydraulic control systems with a particularly relevant means for investigating dynamic performance as he designs a proposed system. The bond graph modeling technique followed by digital simulation of the model is applied to a hydraulic system proposed for a particular task. Predicted response and subsequently measured response are given, compared, and discussed. Only generally available data and parameter assessment procedures were used for the prediction.
