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.

Modelling and simulation of an electro-hydraulic mining manipulator
Proceedings of International Conference on Robotics and Automation, 2002A method for modelling an electrohydraulic system is presented in this paper. Without directly using the conventional linear models, accurate models for the electrohydraulic components have been constructed using the characterisation data provided by manufacturers and measurements obtained in the laboratory with a custom built electrohydraulic ...

Projective control of electro-hydraulic servo system
Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001A 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.

Electro-hydraulic dipole vibrator
The Journal of the Acoustical Society of America, 1993A downhole seismic shear wave source is used to generate seismic shear waves a downhole environment. At least one double headed piston rod with a third piston on the center of the rod slides laterally in the downhole tool. Each end piston head is connected to a rolling diaphragm that is secured at its edges around the periphery of the piston receiving ...

Identification and control of a motorcycle electro-hydraulic clutch
2012 IEEE International Conference on Control Applications, 2012This paper addresses the identification and control of a motorcycle electro-hydraulic clutch, to be employed as main actuator for the design of future automatic gear shift controllers and launch controllers. These applications have very different requirements in terms of tracking performance, and designing an effective controller for both working ...

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.

Electro-hydraulic valve control with multiair technology
MTZ worldwide, 2009Over the last decade, the development of new common rail technology for diesel engines marked a breakthrough in the passenger car market. In order to secure the future of petrol engines, Fiat Group decided to follow the same approach. The company is now launching an electro-hydraulic valve control system called „MultiAir“ into series production.
