Abstract
Disclosed embodiments relate to apparatuses, methods, and systems for restarting an induction machine. In some embodiments, a method includes estimating a position of a rotor and a speed thereof in a position and speed estimation Operation, resetting a speed reference to correspond to the speed of the rotor in a speed reference resetting Operation, generating a control voltage corresponding to the speed reference to regulate a voltage magnitude using the control voltage in a voltage magnitude regulation Operation, and re-accelerating the induction machine up to a target speed after the regulation of the voltage magnitude in a re-acceleration Operation.
