controle de corrente, motor de seis fase, tolerância a faltasAbstract
Este trabalho investiga estratégias de controle de tensão e corrente de um motor de seis fases operando sob condições de falta. As estratégias de controle permitem a operação contínua e livre de perturbação do sistema de acionamento sem conexões adicionais de hardware com a perda completa de um braço do inversor ou fase do motor. As estratégias de controle apresentadas aqui são indicadas para operação sem ou com malha de controle de corrente (iguais ao controle Volts/Hz e controle vetorial com orientação pelo campo). Uma análise completa dos controles em tensão e corrente são apresentadas. Resultados de simulação e Experimentais demonstram a validade dos sistemas propostos.
