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

Dynamic Response Analysis of Control Loops in an Electro-Hydraulic Servo Pump Control System
Processes, 2022 An electro-hydraulic servo pump control system realizes the basic action of a hydraulic cylinder by controlling the servo motor, which effectively improves the problems of a traditional valve control system such as high energy consumption, low power-to ...

A Novel Multifunctional Energy-saving Electro-hydraulic Servo System
2021 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2021Traditional electro-hydraulic servo system with only one proportional directional valve has low control freedom, which makes it unable to adapt to the complex and variable load conditions and causes serious energy waste. To solve this problem, a new multifunctional energy-saving electro-hydraulic servo system is proposed.

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.
