Curvas de Magnetizac¸a˜o, Ma´quina de Relutaˆncia Varia´vel, Smoothing SplinesAbstract
Este trabalho apresenta em detalhes um sistema automa´tico que permite obter as curvas de magnetizac¸a˜o da ma´quina a relutaˆncia varia´vel (MRV). Sa˜o estudadas te´cnicas de interpolac¸o˜es no processamento dos dados dos ensaios para obter o modelo na˜o linear de uma MRV 12/8. E´ proposto o uso da te´cnica smoothing splines que permitiu obter um modelo preciso e condizente com o funcionamento da MRV. Resultados de simulac¸o˜es e ensaios experimentais confirmaram a eficieˆncia do sistema e a importaˆncia da obtenc¸a˜o de curvas reais quando se deseja ter modelos precisos de uma MRV.
