—What the authors propose in this paper is an intelligent method to use submodels of Petri net type in order to model complex discrete event systems (DES). Starting from the definition of the Petri network, a clear definition of submodels of such networks is proposed by the authors. The use of submodels in DES' analysis is exemplified by modeling of… (More)
— The paper establishes a preliminary pragmatic method to obtain the control strategy of an innovative small windgenerator prototype. There is presented the proposed structure of the considered wind energy conversion system, respectively its components and subsystems. There were considered the wind turbine, the generator, the electronic converters, the… (More)
Chaotic behaviors of the buck converter were demonstrated by computer simulation studies. The paper implied theoretical considerations and simulations for this kind of converter using a sliding-mode control. The method tried to establish a periodic behavior from a chaotic one in converter behavior.
