    Sensitivity minimization by stable controllers for a class of unstable time-delay systems
    (IEEE, 2006) Gümüşsoy, S.; Özbay, Hitay
    In this paper sensitivity minimization problem is considered for a class of unstable time delay systems. Our goal is to find a stable controller stabilizing the feedback system and giving rise to smallest H∞ norm for the sensitivity function. This problem has been solved by Ganesh and Pearson (1986) for finite dimensional plants using Nevanlinna-Pick interpolation. We extend their technique to include possibly unstable time delay systems. Moreover, we illustrate suboptimal solutions, and their robust implementation.

    Sensitivity minimization by strongly stabilizing controllers for a class of unstable time-delay systems
    (Institute of Electrical and Electronics Engineers, 2009) Gumussoy, S.; Özbay, Hitay
    Weighted sensitivity minimization is studied within the framework of strongly stabilizing (stable) Hinfin controller design for a class of infinite dimensional systems. This problem has been solved by Ganesh and Pearson, for finite dimensional plants using Nevanlinna-Pick interpolation. We extend their technique to a class of unstable time delay systems. Moreover, we illustrate suboptimal solutions, and their robust implementation.
