Analysis of Electro-Hydraulic Car Steering Systems
2005There have been great reserch efforts in order to improve present power-assisted steering systems for passenger cars. The description of main types of power-assisted steering systems are given. The focus of the paper is on electro-hydraulic steering systems that seems to be employed in middle and upper class of passenger cars, at least in closer future.

Pressure feedback effects of electro-hydraulic actuator system
2014 11th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2014Vibration 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 identification and control of an Electro-Hydraulic Actuator system
2012 IEEE 8th International Colloquium on Signal Processing and its Applications, 2012Precise 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.

Electro-Hydraulic Camless Valvetrain System Modeling
Advanced Vehicle Technologies, 2001Abstract 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.

Modelling of an electro-hydraulic servo-system
1977Many 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 ...
