In this paper, a real time sliding mode control scheme for a variable speed wind turbine that incorporates a doubly feed induction generator is described. In this design, the so-called vector control theory is applied, in order to simplify the system electrical equations. The proposed control...

The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a sliding mode control for variable speed wind turbine that incorporates a doubly fed induction generator is described. The electrical system incorporates a wound...

Prediction of demand is a key component within supply chain management. Improved accuracy in forecasts directly affects all levels of the supply chain, reducing stock costs and increasing customer satisfaction. In many application areas, demand prediction relies on statistical software which...

В статье рассматривается класс совокупностей технологий, которые могут быть представлены как сложные социально-экономические системы. В качестве инструмента...

In this article, author considers a class of technologies aggregates, which can be present as complex socio-economic systems. The order parameters are chosen as instrument of reflect the system integrity of this technologies aggregates. The analysis of aggregates through order parameters permit:...

The purpose of this paper is to study a price level dynamics in a simple fourequation model. A basis of this model is developed from dynamical Kaldorian model which could be noticed very frequently in works of non-linear economic dynamics. Our approach is traditional. The difference is observed...

A purpose of this paper is to formulate a continuous dynamical model for a small closed economy with a simple structure and with a minimum number of non-linearities. A basis of this model is developed from dynamical Kaldorian model. Variables in the modified dynamical Kaldorian model are in a...

The purpose of this paper is to study a price level dynamics in a simple four-equation model. A basis of this model is developed from dynamical Kaldorian model which could be noticed very frequently in works of non-linear economic dynamics. Our approach is traditional. The difference is observed...
