Dissertação (Mestrado em Engenharia Elétrica e da Computação) - Universidade Federal de Goiás, Goiânia, 2021.http://repositorio.bc.ufg.br/tede/handle/tede/11547This work presents a method of Field Oriented Control and torque ripple minimization for Variable Reluctance Machines. It utilizes a non-sinusoidal generalised Park transform, also known as dqx transform, and the derivatives of inductance of the machine as state variables. As a consequence, the mathematical formulation becomes simpler than previous works in literature, which use the traditional Park transform. To validate the method proposed, phase inductances and its derivatives for a 6/4 machine were obtained from Finite Element Analysis simulations and used in the calculations. Magnetic saturation effects were also considered. The mathematical formulation, numeric and simulation results are shown. Simulation results demonstrate that the method proposed in this work effectively reduced torque ripple by 2.9 times, torque ripple factor was reduced by 4.65 times and Joule Effect losses are decreased by 79.68% in comparison with conventional driving strategies. Flux weakening and flux enhancement simulations were also performed and showed that machine speed increased up to 19.22% with respect to base speed.Attribution-NonCommercial-NoDerivatives 4.0 InternationalVariable reluctance machinesField oriented controlVector controlTorque ripple minimizationField weakeningField enhancementMáquinas de relutância variávelControle de orientação de campoControle vetorialMinimização de oscilações de torqueEnfraquecimento de campoENGENHARIAS::ENGENHARIA ELETRICADissertação
