    PID controller design for fractional-order systems with time delays
    (Elsevier, 2011-11-22) Özbay, Hitay; Bonnet, C.; Fioravanti, A.R.
    Classical proper PID controllers are designed for linear time invariant plants whose transfer functions are rational functions of sα, where 0<α<1, and s is the Laplace transform variable. Effect of inputoutput time delay on the range of allowable controller parameters is investigated. The allowable PID controller parameters are determined from a small gain type of argument used earlier for finite dimensional plants.

    Reliable decentralised control of delayed MIMO plants
    (Taylor & Francis, 2010-03) Gündeş, A. N.; Özbay, Hitay
    Reliable decentralised proportional-integral-derivative controller synthesis methods are presented for closed-loop stabilisation of linear time-invariant plants with two multi-input, multi-output (MIMO) channels subject to time delays. The finite-dimensional part of plants in the classes considered here are either stable or they have at most two poles in the unstable region. Closed-loop stability is maintained with only one of the two controllers when the other controller is turned off and taken out of service.
