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 Wit et al. (1996) are generalized. A Lyapunov function which provides a global stability test and allows to compute robustness margins is given. Different mechanisms for the loss of stability are detected by means of bifurcation analysis. Robustness margins and design guidelines are derived from these results
