Abstract
A method of a sensorless indirect rotor-fieldoriented control of a dual stator induction motor with magnetic saturation is proposed in this paper. Magnetic characteristics of the dual stator induction motor indicate a nonlinear behavior. The computational electromagnetic d-q model when the dual stator are fed by an independently current-controlled pulse width modulation (PWM) two identical three-phase voltage source inverters. By controlling the machine's phase currents, harmonic elimination and torque ripple reduction techniques could be observed. The unbalanced current sharing between the dual stator winding sets is eliminated. High accuracy and performance is obviously demonstrated by comparing experimental and simulation results both in electromagnetic and dynamic features.
