Abstract :
A simple, high-performance flux control scheme for an induction motor is proposed. The flux in this drive is maintained constantly and controlled directly without any coupling to drive the induction motor like a DC motor. The ripple current in this scheme is bound using a double hysteresis loop (or delta modulation) to control the flux and the stator current simultaneously. It is verified by simulation that the drive system using these methods operates well and has good dynamics in near zero speed as well. The simulation results are confirmed by experiment
