Abstract :
A new induction machine model that includes the effects of magnetic saturation is developed through magnetic circuit modeling. The new model has advantages for use in designing control systems, and is applied to the design of field-oriented control schemes for saturated machines. The control methods are extensions of standard field-oriented methods for linear-magnetics machines, but remove cross coupling between rotor flux control and torque control that are produced by magnetic saturation. An observer for estimating rotor flux is also discussed. Experimental results verifying operation of the proposed control method are presented
