A Study on the Electro-Hydraulic Coupling Characteristics of an Electro-Hydraulic Servo Pump Control System

open access: yesProcesses, 2022
Electro-hydraulic servo pump control belongs to an electro-hydraulic coupling motion control system, which involves the mutual penetration and integration of mechanical, hydraulic, electrical, control, and other disciplines, as well as the time-varying, uncertain, multisource, and multifield problems of the internal and external excitation of the ...

Experimental Verification of An Electro-Hydraulic Actuation System Driven by An Integrated Electro-Hydraulic Unit

International Journal of Fluid Power, 2023
This paper proposes an electro-hydraulic actuator (EHA) system, and a novel-designed electro-hydraulic unit (EHU) consisting of a fixed-displacement hydraulic gear machine and a variable-speed electric machine. The novel EHU design integrates an electric machine and a hydraulic machine in a single housing, targeting optimal compactness, power density ...

The electro-hydraulic valvetrain system

MTZ worldwide, 2004
The electro-hydraulic valvetrain system (EHVS) is one of the most flexible options for replacing 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.

Intelligent PID control of an industrial electro-hydraulic system

ISA Transactions, 2023
In this study, an intelligent PID (i-PID) controller is designed for position control of a nonlinear electro-hydraulic system with uncertain valve characteristics and supply pressure variations. The proposed controller uses estimation of ultra-local model of the system.

Projective control of electro-hydraulic servo system

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
A nonlinear dynamic model for an electro-hydraulic servo system is developed. The model's response is compared with that of an actual valve. A projective control algorithm is used to control the motion of a load. Robustness of the control algorithm is analyzed through simulations.
