Hydraulic systems are widely used in Engineering because they are highly versatile and can be combined with other domains of physics (mechanics, electronics, etc.). For this reason, it is of vital importance to study and develop them with a view to obtaining mechanicalhydraulic systems that are increasingly efficient. The beginning of this paper briefly analyses the method usually used to perfo...

The dynamics of hydraulic systems are highly nonlinear and the system may be subjected to non-smooth and discontinuous nonlinearities due to directional change of valve opening, friction, etc. Aside from the nonlinear nature of hydraulic dynamics, hydraulic servo systems also have large extent of model uncertainties. To address these challenging issues, a robust state-feedback controller is des...

The Doctorate in Environmental and Infrastructure Engineering has been operating since the academic year 2008/2009. The program introduces doctoral students to the world of research on key theoretical and technological elements associated with water, environment, hydraulic and transportation infrastructures, geology, as well as geomatics. In this context, the program is grounded on environmenta...

In the present work, we use an adaptive robust approach for fault detection and accommodation in electro-hydraulic systems. It is well known fact that any realistic model of a hydraulic system suffers from significant extent of uncertain nonlinearities and parametric uncertainties. An adaptive robust scheme is robust to such uncertainties and tracks the change in parameters reliably. Consequent...

In an open channel, a sudden rise in water level induces a positive surge, or bore, that may develop as a hydraulic jump in translation. When the surge propagates against an adverse slope, it decelerates until it becomes a stationary hydraulic jump. Both hydraulic jumps and decelerating surges induce some intense turbulent mixing and have some major impact on the sediment transport in natural s...

ABSTRACT: The requirements and basic components of a typical optimal control environment for water-supply pumping systems are presented and discussed. Examined model components include hydraulic network models, demand forecast models, and optimal control models. A review of existing optimal control methodologies for water-supply pumping systems is also provided. Examined methodologies are class...
