| Zusammenfassung: | The control device (4) carries out a control of the induction machine (1) based upon a flux estimation performed by means of a Luenberger state observer (6), the estimation error of which can be defined by means of a matrix (Ao) having a plurality of eigenvalues (po), the magnitude of each of which is proportional to the magnitude of a respective pole (p) of the induction machine (1), and the phase of each of which is rotated with respect to the phase of the corresponding pole (p) of the induction machine (1) by a given angle of rotation ( ). |
