    摘要: Methods and apparatuses for substantially eliminating torque pulsation in a doubly fed induction machine are disclosed. An example method comprises: measuring a stator current of the doubly fed induction machine, measuring a rotor current of the doubly fed induction machine, calculating a total magnetic flux density in an airgap of the doubly fed induction machine, calculating a tangential force density, calculating an electromagnetic torque, repeating the calculation of the electromagnetic torque over one electrical cycle to estimate a torque pulsation, determining a new rotor current that substantially eliminates the torque pulsation by referencing a set of optimal rotor currents in a look-up table, and changing the rotor current in response to the determination. Other embodiments are described and claimed.
