Research paper thumbnail of FEM-coupled simulations and genetic algorithm model applied to reduce the torque ripple of a 2-phase SR motor drive

To implement the power electronic motor drive model and the optimisation procedure, it was used, respectively, with coupled FEM simulations resources and a MATLAB Script. In this work, they were tested with two inverter commutation strategies whose values were validated through the comparison with the experimental results. The simulated and experimental values converge in the same direction, validating the proposed methodology.

The paper presents the simulations of the motor and generator in the single-pulse operating modes. An approach of the motor operating in the chopping-voltage mode is also presented. The simulations were conducted considering constant rotor speed and the software takes advantage of the rotating air-gap method.

Through Imagineering (the business department and project management program), The Walt Disney Company has done this alignment in an exemplary way. Using a theoretical investigation, this study analyzed the Imagineering as a reference in strategic management of global projects through Disney´s business portfolio, a global benchmarking and with Malmberg et al. (2010) as a company guide. As the main results of the correlations carried out, it was noted that the Imagineers who work in project teams apply tools and techniques with a strategic vision focused on differentiation, generating value, and mixing imagination with technical capacity. The Blue Sky department and its integrated units make possible the creation and deployment of the attractions, the theme parks, hotels, resorts and the Disney sea cruises, demonstrating in this way, to be a highly effective project management office.

Using a theoretical investigation, this study analyzed Imagineering as a reference in strategic management of global projects through Disney´s business portfolio, a global benchmarking and with Malmberg et al.

The increase in the number of switches is acceptable since a standard full bridge transistor module is used. The paper also shows the commutation and control strategy applied to these topologies. These topologies can be used to produce low-power,

A switched reluctance motor/generator -SRM/G -with 3 phases, 6 stator poles and 4 rotor poles is connected to the DC link bus through an asymmetric half-bridge converter which is fed by a PEM (Proton Exchange Membrane) fuel cell. The control functions of this drive are performed by an 8-bit microcontroller. This system is designed to allow the studies of the motoring, generating and regenerative braking operations aiming the development of the necessary knowledge to design propulsion systems for several kinds of vehicles. Some simulations and tests results are also presented.
