A modern method for field-oriented control of saturated induction machine

Presents a method for field-oriented control of saturated induction machines. The proposed method is based on a model that utilises the angular speed of air-gap magnetising flux instead of magnetising current derivatives (classical method). Because the volume of calculations is seriously reduced, this method is an important contribution to the intelligent control of induction machines. By adequate selection of orientation variables a simple way for dynamic decoupling of mechanical state and magnetising state is obtained. Simulation results have shown high dynamic and stationary performances and a good decoupling even in the case of very strong requirements for the drive system.
