The paper discusses the influence of core loss on accuracy of rotor flux oriented control, applied in conjunction with current fed induction machines. A mathematical model that accounts for core loss is derived and it is shown that control structures that neglect core loss cannot provide truly decoupled control of the machine flux and torque. Consequently, some amount of detuning will always exist, purely due to the assumption that core loss can be neglected, unless some mean of compensation is introduced. The actual detuning is evaluated for steady-state operation of an indirect rotor flux oriented current fed induction machine. A modified indirect vector controller is then proposed, which is capable of compensating for core loss in steady-state operation. The accuracy of core loss modelling and practical difficulties in implementation of modified control structures are addressed as well. |
