Modelling and LPV control of an electro-hydraulic servo system [PDF]
2006 IEEE Conference on Computer Aided Control System Design, 2006 IEEE International Conference on Control Applications, 2006 IEEE International Symposium on Intelligent Control, 2006 This paper aims to show the modelling and control of an hydraulic servo system, targeting at frequency domain based controller design and the implementation of a LPV controller. The actual set-up consists of a mass, moved by a hydraulic cylinder and an electro-hydraulic servo valve.

Advanced Photonics Research, Volume 6, Issue 12, December 2025.Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital

POSITION CONTROL OF ELECTRO-HYDRAULIC SERVO SYSTEM WITH FRICTION COMPENSATION
EPRA International Journal of Multidisciplinary Research (IJMR), 2023 This work presents a model-based friction compensation technique and an integral adaptive backstepping controller to improve the position control of the electrohydraulic servo system. The controller design uses a continuous approximation of the LuGre friction model and the Lyapunov theory of nonlinear systems.

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 800-815, December 2025.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Engineering Reports, Volume 7, Issue 12, December 2025.This paper proposes N,N′‐DMEA to inhibit HSGSW corrosion, characterizes its induced mechanical degradation, and identifies the optimum N,N′‐DMEA ratio for HSGSW in cable‐stayed bridge structures. It offers a new technical approach for protecting bridge cable high‐strength steel wires.
