Abstract: In this study the Double Fed Induction Machine (DFIM) is controlled by passivity. The idea of passivity is based on the use of Euler-Lagrange principle of machine total energy exploitation. This structure presents very important advantages for nonlinear systems, specially in the trajectory tracking to insure the desired operation. Presented results show the passivity efficiency when applied to DFIM in separated frames, not only from stability point view but also robustness of model parameters variations is concerned. These advantages encourage an easy practical implementation for optimal loaded DFIM performance with variable references.
