Necessity for a Transition to Generalized Parameters in Studying the Dynamics of Electrohydraulic Servo Drives

In this paper, results in the form of generalized dynamic characteristics of drive stability and response are presented. For the first time in a numerical study of electrohydraulic servo drives, a transition from initial variables to generalized ones is applied. Based on the presented criterion and dependences obtained as a result of numerical solutions of such equations, it has been possible to generalize the calculated patterns and reduce them to a specific class of phenomena. Furthermore, in the studied range, the identified criterion dependences are equivalent to analytical expressions, based on which it has been possible both to determine the response in transient conditions for systems of any order and to draw the most general conclusions.
