In this paper, an Active Queue Management (AQM) robust control strategy for Traffic Control Protocol (TCP) data transfer is proposed. To this purpose, the TCP behaviour is first approximated by a second order model with delayed input obtained from the linearization of an efficient and commonly used nonlinear fluid-based model. The adopted feedback control structure uses a fractional-order Pl controller. To ensure the desired robustness the parameter regions where such a controller guarantees a given modulus margin are derived. An example commonly used in the literature is worked out to show that the suggested graphically- based design technique is simple to apply while it limits the effects or disturbances and unmodelled dynamics.

This paper deals with the robust control of time-delay non-integer order plants by means of standard non-integer order controllers. Precisely, a method for determining the parameter regions where a PIλDμ controller ensures a given modulus margin (inverse of the H∞ norm of the sensitivity function) is presented. This method, which is conceptually simple and intuitive, extends to the aforementioned general classes of controllers and plants the approach recently followed by the present authors in the integer order case. A Matlab program to plot the loci of constant modulus margin and those of constant crossover frequency has been developed and applied to some numerical examples taken from the literature.
