Fractional order PF controller applied to the induction machine current loop

Abstract:

This paper investigates the use of fractional order PIα controllers, applied to inverter driven induction machines. Fractional order controllers provide additional degrees of freedom for their design, and the non-linearity introduced by the fractional part of the controller provides better tuning for the operation of the controller. In this work a fractional PI controller is applied to the current loop of a vector controlled induction machine and the results are compared to the ones obtained with a conventional PI controller.
