Control of DFIM Machine with Fractional PIλDμ controllers

Abstract

Fractional order PIλDμ controllers are the most common fractional order controllers used in practice. The proposed method is useful in designing fractional order PID controllers for a Doubly Fed Induction Machine (DFIM). Ourobjective is to develop robust controller that ensure good robustness stability and performances. Fractional order PID parameters are obtained by minimization a coast function (Standard H∞ problem) with MIN-MAX algorithm. Finally, numerical results are given to show the effectiveness of the fractional order PIλDμ controllers over their H∞ (LMI’s) method.
