Dynamic performance of a nonlinear non-dimensional two stage electrohydraulic servovalve model
Source abstract
Abstract
Electrohydraulic servosystems are commonly used in various engineering applications due to their high power-to-weight ratio, good performance, and ease of control. An electrohydraulic servovalve is an essential item of fluid power servomechanism where fast response, high power output and working fidelity are necessary. A full description of the dynamic performance of a two stage electrohydraulic servovalve is presented. Nonlinear Non-dimensional mathematical model has been developed for that purpose. The system main equations could be derived in minimal symbolic forms; which facilitates a subsequent numerical simulation in order to investigate the static and dynamic behaviors. In addition to a step response, ramp and sinusoidal inputs responses are investigated. The model has been coded in the software package Matlab/Simulink (Liuping, Modern control systems analysis and design using Matlab and Simulink, Springr-Verlag, London, 2009). The use of the non-dimensional form enables designer to expect the valve behavior of the same shape but with different sizes.
