Fractional-order integral and derivative controller design for temperature profile control

This paper presents a strategy to tune a fractional order integral and derivative controller satisfying gain and phase margins. The closed-loop system designed has a feature of robustness to gain variations with step responses exhibiting a nearly iso-damping property. This paper aims to apply the tuning procedure proposed to temperature control at selected points in Quanserpsilas heat flow experimental platform. From the comparison with the traditional PI/PID controller based on Ziegler Nicholpsilas tuning method, the effectiveness and validity of the proposed methodologies are illustrated.
