A vector-control system and method of a 'sensorless' type for electric drives with a.c. motors is based upon generation of an oscillating magnetic field and upon measurement of the deviation, with respect to said oscillating field, of the flux generated thereby on account of anisotropy, whether natural or induced, of the magnetic structure of the machine.

Control system and method for electric drives with a.c. motors

A system and a method of vector sensorless control for electrical drives with induction motors, based on the generation of a high frequency rotating magnetic field which, by composing with the main magnetic field, produces a change of the saturation level as a function of the relative positions taken during the motion. Variation of the saturation level produces a modulation of the zero sequence component of the stator voltage, which is used to evaluate the position of the main field.
