Abstract :
In the present work, the robust current controller design for AC induction motor is addressed. It replaces current PI controllers in classical vector control algorithm where the controllers operate in coordinates fixed to rotor flux. AC induction motor parameters are treated as parametric uncertainties. Their mutual dependencies are studied so as to simplify complex AC induction motor state space description and to make the controller design using D-K iteration treatable. Imprecision in decoupling is partially treated. The newly designed controller is compared with the classical vector control algorithm.
