Control Systems Chapter Webinar | Interpolation-based Design of Stabilising Controllers for Retarded and Neutral Delay Systems by Prof Hitay Ozbay


A class of retarded and neutral time-delay systems will be considered: the plant may have finitely many or infinitely many unstable poles. Stabilising controllers are obtained from two different types of interpolation-based designs. Robustness to uncertainties in the interpolation will also be discussed.

A parameterisation of all stabilising integral action controllers is obtained. Examples are given to illustrate this simple design procedure.
