Document Type and Number:

Japanese Patent JP3054510

Kind Code:

B2

Abstract:

There is disclosed a method of controlling an induction motor, which controls a primary current of the induction motor on the basis of a magnetic flux component current command i1d*, a torque component current command i1q*, and a slip frequency command omega s which are orthogonal component command values of the primary current of the induction motor, wherein control parameters R2*, l2 * and M* set in accordance with a secondary resistance R2, a secondary leakage inductance l2 and a mutual inductance M of the induction motor are used to calculate the magnetic flux component current command i1d*, the torque component current command i1q* and the slip frequency command omega s. Even in the case where the mutual inductance M of the induction motor varies, if the coefficient 1/M* is assumed as a magnetic saturation function given by a gap magnetic flux, the influence of the magnetic saturation can be canceled.
