This paper presents the theoretical basis that models the behavior of The switched reluctance machines and their drives. The general characteristics, the differential equation system that constitutes the mathematical model of the motor and the Simulink's blocks, which have been built for running the simulation, are outlined. The results of the simulation have been shown and compared with those obtained experimentally. The Simulink model is used for studying the Switched Reluctance motor drive behavior under some operation conditions and theoretical explanations for the simulation's results are given in every case.

The article presents an experiment which explores areas of high yields work in the system of electro-hydraulics. It performs an identification of the subsystems of the induction motor using centrifugal pump that transports pulp latheritic hydromixes. A fuzzy algorithm is shown, which correlates the functions offered from losses based on the moments equation of electric drives with the purpose of minimizing the input power from the experimental and technological context of the system.

The article examines the significance of fuzzy logic control algorithm, which offers the specificities of the electric subsystem and mechanic of the operations. According to the authors, it is of interest a block compensator of the electromagnetic torque that improves the work of the fuzzy controller's before the cavitation phenomena. Experimental results are shown with the controller operating at the leaching plant of the Ernesto Che Guevara Corp.

In this article, it will be carried out an itemized analysis of the welding sources evolution in their last stage, to outline the future forecasts that are expected in this field that so much importance has at the present time. On the other hand, and keeping in mind the new requirements of efficiency and reliability that are demanded to the welding sources, is necessary to analyze if the technology of production of these sources is as mature as it is said or it is necessary to impel it more in some concrete aspects of the same one.

The fundamental idea of this article is to control a steps motor using the parallel port of a computer and demonstrate the temporary efficiency of the applications that are executed in prepared systems to execute tasks of real time. To take advantage of to the maximum capacity of strict real time that RT-Linux offers us for the control of electric workings. A small software is developed in language C that sent the signs to the parallel port in the necessary time. This software is not designed with commercial, only allows to carry out tests on the control circuit designed for this purpose. [ABSTRACT FROM AUTHOR]

In this article is tested a virtual controller using fuzzy logic for a hybrid system of power generation. LABVIEW is used as a digital simulation tool obtaining descriptive graphical results of the action of the driver as well as a graphical interface of the behavior of the system. [ABSTRACT FROM AUTHOR]
