Pressure feedback effects of electro-hydraulic actuator system

2014 11th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2014
Vibration test of electro-hydraulic actuator is widely used in the field of industry like large dynamic system to guarantee the performance of the system. As the system is working under the high speed condition, the dynamic vibration test is required naturally.

System Analysis of Electro-hydraulic Control Systems

1991
The system analysis introduced in the previous chapter will now be expanded to cover several types of electro-hydraulic control systems. The method described in Chapter 11 is not suitable for the analysis of control systems incorporating flow feedback elements referred to in Chapters 5 and 6.

The Electro-Hydraulic Valvetrain System EHVS - System and Potential

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">The electro-hydraulic valvetrain system (EHVS) is one of the most flexible options to replace the conventional mechanical camshaft by an electronically controlled actuator system. Thus, fully variable feeding and dissipation of the gases involved in the combustion process can be ensured.</div> <div class ...

System identification and control of an Electro-Hydraulic Actuator system

2012 IEEE 8th International Colloquium on Signal Processing and its Applications, 2012
Precise control of Electro-Hydraulic Actuator (EHA) system has been a challenging task due to nonlinearities, time varying characteristics and uncertainties of the system. A controller can be designed when given accurate model of the system. This paper presents the process to obtain an EHA system's model using system identification approach.

Energy Consumption of Electro-Hydraulic Steering Systems

SAE Technical Paper Series, 2005
<div class="htmlview paragraph">The reduction of fuel consumption in vehicles remains an important target in vehicle development to meet the carbon dioxide emission reduction target. One of the significant consumers of energy in a vehicle is the hydraulic power-assisted steering system (HPS) powered by the engine belt drive.

Modelling of an electro-hydraulic servo-system

1977
Many theoretical models have been developed to simulate the performance of hydraulic Control components and systems, but all are limited by the assumptions involved and uncertain factors associated with practical hydraulic systems. Authors warn that seal compressibility, inertia of oil in lines, mounting compliance, structural damping, friction and ...

Electro-Hydraulic Camless Valvetrain System Modeling

Advanced Vehicle Technologies, 2001
Abstract This report describes a development of Matrixx model of prototype Electro-hydraulic Camless Valvetrain (ECV). The model was developed using bond graph techniques and was partially validated with respect to limited available experimental data for a single-cylinder laboratory implementation.
