The research work carried out within the OFT-project shall provide insights, methods, and prototypic software to support the design of hydraulic closed loop control systems. The paper in hand presents an overview of the research work, motivates the current objectives of the project, and provides useful background information. In particular we develop different views of the hydraulic design proc...

It discussed the Governing system used in Thermal Power Plant with Electro-Hydraulic controller with its design, construction and advantages where it indicates that EHTC System which protects and controls Governing of Steam turbines. This paper ind...

The design of stabilization ponds for the treatment of wastewater is traditionally based on empirical guidelines. Even more the hydraulic design is normally over simplify. However, the performance of a pond will highly depend on the proper hydraulic design. This paper present an approach that combines the traditional empirical design with the use of modelling tools to predict the performance of...

This paper is concerned with real-time optimal-tuning PID control design for industrial hydraulic systems. Several optimal-tuning controller design techniques are used for a hydraulic position control system. After analysis on the system, a nonlinear dynamical model is derived. A nonlinear PID control scheme with inverse of dead zone is introduced to overcome the dead zone in this hydraulic sys...

abstract the temperature of water entering the soil or variation in soil temperature has a direct impact on soil hydraulic conductivity via the effect on water viscosity. in this research, the time variability of soil saturated hydraulic conductivity (ks) was studied. the relation between soil temperature and fluid viscosity with hydraulic conductivity were also studied. the necessary experimen...

This article presents the identification and control of an electro-hydraulic crane. The crane is of the type used on forestry vehicles known as forwarders, which travel off-road collecting logs cut by the harvesters. The dynamics identified include significant frictional forces, dead zones, and structural and hydraulic vibrations. The control algorithm proposed, comprised of a linear controller...

The design process of hydraulic drives requires a lot of knowledge and experience although many computer tools are available that aid in various aspects of the design. One of these aspects is the selection of a suitable control strategy and its parameterisation. While being a significant key for the performance of servo-hydraulic drives it is nevertheless often neglected because of lack of know...
