The specific problems of the disconnection of HVDC breakers need an analysis of performances at laboratory scale. In the study of hybrid circuit breakers with commutation, three steps are necessary: modeling, simulation and experimental tests. The paper presents a modeling procedure for a hybrid commutation breaker intended to operate using resonant circuits phenomenon. Using the Matlab platform,...
This paper presents a Neural Network approach to compensate dynamic terms, friction force in particular, of a rescue walking robot used in haptic interfaces. The impedance control through dynamic compensation of the friction force is studied, followed by the implementation of neural intelligent networks in the feed-forward loop in order to eliminate the corresponding terms in the dynamics, friction...
Due to climate changes that have been observed in regions all over the world and which are believed to be caused by the use of conventional energy sources, we must draw our attention to renewable energy sources which are the most suitable in the future. This paper presents a study about designing and simulation of a small wind-hydro power plant which will be located in the Didactical and Agreement...
