System and method of control for sensorless induction motor drives |
摘要 |
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.
