Abstract :
In this paper, we propose a new control scheme based on Extremum-Seeking (ES) combined with Fractional-Order Systems (FOS). This auto-tuning strategy involving a fractional order integral action, is developed to optimize the system response without external dithering, exploiting disturbances already present in the control system. We show by mean of comparative simulation examples that the proposed fractional order ES control algorithm can improve the plant dynamics with respect to response time and disturbance rejection.
