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...

In this study, we present an alternative maximum power point tracking technique used in a solar water pumping system to produce the for modifying amount of pumped water. This was actually created primarily regulate duty ratio buck converter. order control array operating track point, nonlinear approach based on input–output feedback linearizing and Lyapunov stability theory is used. By adjustin...

The ongoing research aims to develop an optimal variant of the industrial water supply scheme, selected based on a comparison several possible solutions. It is recommended use block-by-aggregate technical system at stations equipped with any number main units large flow pumps, more than 5 m 3 /s. If there significant amount sediment in stations, settling tanks are needed intake devices systems....

A CSS1†is a system with the continues-state components. When a component has the ability to obtain all the situations from completely working to completely failed, it named continues-state component. In the real world, performance rate of elements are continuous and decrease by time. Continuity of components causes infinite working states and grows up the system states. In this paper we propose...

The design, fabrication and characterization of a miniaturized, mechanically-actuated 12-channel peristaltic pump for microfluidic applications and built from simple, low-cost materials and fabrication methods is presented. Two pump configurations are tested, including one which reduces pulsating flow. Both use a monolithic PDMS pumping inlay featuring three-dimensional geometries favourable to...

Numerical investigations are carried out on a linear structure, weakly coupled to a small non-linear attachment. The energy pumping phenomenon corresponds to a controlled one-way channeling of the vibrational energy to a passive non linear structure where it localizes and diminishes in time due to damping dissipation ([1], [2]). So the essential non-linearity of the attachment enables it to res...
