Este artigo analisa o impacto da banda passante dos controladores PI de eixo q e d no comportamento dinâmico do Gerador de Indução com Dupla Alimentação (GIDA) orientado no referencial do fluxo estatórico. Com a conecção direta do estator do gerador a rede elétrica, variações na tensão no Ponto de Conecção Comum (PCC) ou variações da corrente dr i causam oscilações no fluxo estatórico. Essas oscilações podem ser amortecidas através da escolha adequada da banda passante dos controladores PI de eixo q e d. Além disso, este artigo contribui com uma análise e metodologia de projeto que garante a estabilidade e bom desempenho do estimador não linear utilizado para obter a posição do fluxo estatórico. Para validar a análise são mostrados resultados experimentais obtidos a partir de um conversor trifásico com modulação Space Vector totalmente controlado através do DSP TMS320F241.
