Cancellation controllers can be realizable for induction motor drives, but unfortunately, parameter variations, especially rotor resistance, de-tune the control action. However it is shown by linearized analysis that this drawback can be overcome, except for flux variations, using conditioned feedback loops. Starting from a nonlinear indirect field oriented controller already proposed by the authors for compensating flux magnitude variations an improved control system is presented having a conditioned feedback loop.

Abstract
Cancellation controllers can be realizable for induction motor drives, but unfortunately, parameter variations, especially rotor resistance, de-tune the control action. However it is shown by linearized analysis that this drawback can be overcome, except for flux variations, using conditioned feedback loops. Starting from a nonlinear indirect field oriented controller already proposed by the authors for compensating flux magnitude variations an improved control system is presented having a conditioned feedback loop. Computer simulation results show the better performances obtainable with this control system.File in questo prodotto:
