Abstract
The influence of the rotor time constant mismatch on the stability of induction motors under indirect field-oriented control is analyzed. The results of De Wu et al. (1996) are generalized. A Lyapunov function which provides a global stability test and allows us to compute robustness margins is given. Different mechanisms fur the loss of stability are detected by means of bifurcation analysis. Robustness margins and design guidelines are derived from these results
