A method for estimating a position of a rotor in a motor, with a transient and systems thereof

摘要

At least one exemplary embodiment discloses a method for estimating a position of a rotor in a motor. The method comprises a obtaining a current as a rule, the quality index based on a current instruction and a measured current, determining an estimated position of the rotor as a rule, on the basis of the current quality index and the position estimation data and control of the engine based on the estimated position of the rotor.
