The electro-hydraulic valvetrain system
MTZ worldwide, 2004The 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.

Electro-Hydraulic Braking System Modelling and Simulation
SAE Technical Paper Series, 2003<div class="htmlview paragraph">The first step toward a braking system ‘by wire’ is Electro-Hydraulic Braking System (EHB). The paper describes a method to evaluate through virtual experimentation the actual improvement in vehicle behaviour, from the point of view of both handling and comfort, including also pedal feeling, due to EHB.

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 ...

Motion synchronization for multi-cylinder electro-hydraulic system
2001 IEEE/ASME International Conference on Advanced Intelligent Mechatronics. Proceedings (Cat. No.01TH8556), 2001Abstract This paper presents a nonlinear control algorithm to address the motion synchronization problem for a multi-cylinder electro-hydraulic (EH) system. A 2-step design approach is applied such that it utilized linear MIMO robust control technique to design an outer loop motion synchronization controller.

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.

Intelligent-PI controller for electro-hydraulic system
2016 4th International Conference on Control Engineering & Information Technology (CEIT), 2016Electro-hydraulic actuators have been widely applied in industry with position or pressure control. Nevertheless, the conventional linear control technology is not able to satisfy the requirement of improving the control precision due to the nonlinearities of hydraulic systems. This paper presents two control strategies based on intelligent-PI in order

Intelligent PID control of an industrial electro-hydraulic system
ISA Transactions, 2023In 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.
