Robustness Investigation for MRAC Control of a Doubly Fed Induction Generator in a Wind Energy System Based on Fractional-Order Integrators
The aim of this paper is to enhance the performances of active and reactive power control of doubly fed induction generator (DFIG) in systems of wind energy using a design of fractional order model reference adaptive control (FOMRAC) scheme. A fractional order integrator is introduced in the parameters updating adaptation law. The generator is modelized and a standard MRAC controller is designed for comparison sake. Then, a fractional order adaptive FO-MRAC configuration is applied to the energy system in order to improve its performance, by introducing a fractional order integrator. Simulation results give a comparative study based on the quadratic error criterion, in order to illustrate the superiority of the proposed adaptive control scheme.
