English abstract The influence of the rotor time constant mismatch on the stability of induction motors under indirect field oriented control is analyzed. The paper focuses on the global asymptotic stability property and extends the results of []. Robustness margins for global asymptotic stability with respect to rotor time constant mismatches are obtained. The effect of the PI settings in such robustness margins is clarified allowing to derive design guidelines. The methodology is applied to two different induction motor drive systems illustrating the stability margin estimates
Portuguese abstract A estabilidade de acionamentos por orientação de campo indireta de motores de indução quando sujeitos a erros de estimativa da constante de tempo do rotor é analisada. O artigo se concentra na estabilidade global, estendendo os resultados de []. Margens de robustez são determinadas e diretivas para projeto do laço PI de velocidade são obtidas. A metodologia de análise é aplicada a dois sistemas distintos a fim de ilustrar as estimativas de margens de estabilidade
