Servo System of 6 DOF Electro-hydraulic Shaking Table
2011Electro-hydraulic shaking table (EHST) is a useful experimental apparatus to real-time replicate the desired acceleration vibration signal for evaluating the performance of the tested specimen structural systems. A three axis six degree-of-freedom (DOF) EHST system with eight hydraulic actuators is presented in the paper.

Fault Modeling for Electro-Hydraulic Servo System Based on Hybrid System
Advanced Materials Research, 2012A parametric fault model of electro-hydraulic servo system based on hybrid system and multiple linear regression model was put forward. First of all, the operating condition of electro-hydraulic servo system was abstracted to discrete states, then using multiple linear regression algorithm, the model parameter were identified based on the statistical ...

Analysis and compensation for friction in electro-hydraulic servo system
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011Friction in the electro-hydraulic servo system makes tracking and pointing accuracy lower, it is one of the most important influence factors. This paper proposes a nonlinear adaptive friction compensation method based on analysis of the position-control system of valve-control asymmetrical hydraulic cylinder and the LuGre friction model. Dual nonlinear

Observer based feedback linearization control for electro-hydraulic servo systems
2015 International Congress on Technology, Communication and Knowledge (ICTCK), 2015An observer-based feedback linearization control is presented for position tracking of electro-hydraulic servo systems (EHSs). In many hydraulic applications, it is not always possible to measure the full state of the EHS due to cost and space limitation. Therefore, a high gain observer is designed to estimate the full state of the EHS.

Robust Sliding Mode Position Control of Electro-Hydraulic Servo System
2019 International Conference on Electrical, Communication, and Computer Engineering (ICECCE), 2019This article presents the modeling of position tracking robust control strategy for electro-hydraulic servo (EHS) system. To overcome the strong non-linearities and uncertainties in the EHS system, a robust sliding mode controller is used. The tracking performance of the proposed scheme is evaluated for two different inputs i.e. step and sinusoidal. In

Real-Time Modeling of an Electro-hydraulic Servo System
2010Real-Time Hardware-in-the-loop (HIL) test is a good ground for examine the dynamic model of controlled equipments, for example electro-hydraulic servo systems, to observe the main parameters and monitor the dynamic behavior of the system. Electro-hydraulic servo actuators are widely used in industrial applications because it has high moving force ...
