Method for the Field-oriented Control of an Induction Motor

Henrik Rasmussen (Opfinder)

Publikation: Patent


A method for the field-oriented control of an induction motor by means of a frequency contverter is dislosed, in which method a transformation angle is determined by estimation and is corrected in dependence on a rotational speed of a rotor flux vector or of the induction motor and/or in dependence on a delay time. In this connection it is desirable to improve the control behavior. To that end, the transformation angle is corrected a second time to compensate for a phase shift in the frequency converter.
