PC‐based control and simulation of an electro‐hydraulic system
Computer Applications in Engineering Education, 2017AbstractThis article addresses the development of a control system design methodology to make control courses easier to understand. The methodology can be handled in four stages: Modeling, controller design and tuning of the controller gains, simulation, and experimental studies.

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.

System identification and control of an Electro-Hydraulic Actuator system
2012 IEEE 8th International Colloquium on Signal Processing and its Applications, 2012Precise control of Electro-Hydraulic Actuator (EHA) system has been a challenging task due to nonlinearities, time varying characteristics and uncertainties of the system. A controller can be designed when given accurate model of the system. This paper presents the process to obtain an EHA system's model using system identification approach.
