Robust controller design for a flow control problem where uncertain multiple time-varying time-delays exist is considered. Although primarily data-communication networks are considered, the presented approach can also be ...

Stable flow controllers are usually preferred since, compared with unstable flow controllers, they are less sensitive to any modelling imperfections. H-infinity-optimal flow controllers involve finite impulse-response (FIR) ...

According to some recent results, use of non-causal uncertainty blocks may be advantageous in the robust controller design of systems with multiple uncertain time-delays. In this work, performance and robustness improvements ...

Flow controllers are needed to avoid congestion in different types of networks. The dynamics of such networks, however, can usually be represented by infinite-dimensional models, which are either based on partial-differential ...

Robust How controller design problem for data-communication networks with multiple uncertain time-delays is considered. A recent result on the validity of the small gain theorem for systems with non-causal subsystems is ...

An important problem in the operation of data-communication networks is congestion. A tool which is used to avoid congestion is flow control. A flow controller decides on the rate of messages to be admitted to the network ...

An important ptoblem in control engineering is to design a controller which stabilizes a given system and achieves robust tracking of a reference signal despite certain disturbance signals. The present paper considers this ...

Robust stabilizing controller design for neutral time-delay systems with distributed time-delay is considered. The uncertainties in the system are bounded by using a frequency dependent function. This bound is then used ...

Centralized and decentralized robust servomechanism problems for time-delay systems are considered. Sufficient and necessary conditions for the solvability of these problems are presented. The conditions for the two problems ...

Decentralized robust control of infinite-dimensional systems is considered. A decentralized robust controller design approach for such systems is proposed. In this approach, overlapping decompositions is first used to ...
