Linear discrete-event systems and robust servomechanism problem
(IEEE, 1998)Linear discrete-event systems are studied. Reachability, observability, controllability, constructibility, stabilizability and detectability of such systems are investigated. Stability of linear discrete-event systems is ... -
A decentralized control approach for transportation networks
(Pergamon Press LTD, 1999)A decentralized control approach for transportation networks to prevent traffic congestion is presented. The approach was developed by considering flow control and routing control together. The control algorithm is based ... -
Decentralized routing controller design using overlapping decompositions
(Taylor & Francis LTD, 1999)The use of overlapping decompositions in designing routing controllers for large-scale networks is considered and a decentralized dynamic routing controller design strategy is proposed. The strategy is based on the overlapping ... -
Paley inequalities for discrete-time rational orthonormal bases
(Elsevier Science BV, 2000)In this paper, we derive some inequalities which provide information about the Fourier coefficients of linear-time-invariant discrete-time systems with respect to the bounded rational orthonormal basis functions studied ... -
A solution to the robust flow control problem for networks with multiple bottlenecks
(IEEE, 2001)The flow control problem in multi-bottleneck networks is considered. An optimization problem is formulated in order to design decentralized controllers which are robust to time-varying uncertain multiple time-delays. It ... -
On the existence of a disk algebra basis
(Elsevier Science BV, 2000)In this paper, approximation of discrete-time systems by fixed pole orthonormal basis functions is investigated. It is shown that if accumulation points of basis poles do not cover the entire unit circle, then the Fourier ... -
Continuous-time stable and unstable system modelling with orthonormal basis functions
(John Wiley & Sons LTD, 2000)In this paper, model sets for linear time-invariant continuous-time systems which are spanned by fixed-pole orthonormal bases are investigated. The obtained model sets are shown to be complete in the Lebesque spaces L-p ... -
Robust rate-based flow controllers for high-speed networks: The case of uncertain time-varying multiple time-delays
(IEEE, 2000)An H-infinity based robust controller is designed for a rate-feedback flow-control problem in single-bottleneck data-communication networks. The controller is robust to uncertain time-varying multiple time-delays in different ... -
Synthesis of complete rational orthonormal bases with prescribed asymptotic order
(Pergamon-Elsevier Science LTD, 2001)In this paper, a method to construct complete rational orthonormal model sets with prescribed asymptotic order is presented for continuous-time systems. Two special cases that illustrate the application of the method are ... -
Decentralized control design for interconnected discrete-event systems
(Pergamon-Elsevier Science LTD, 2001)Interconnected discrete-event systems are studied in this paper. Petri nets are used to model these systems. A decentralized controller design approach, based on overlapping decompositions, is described for such systems. ... -
Comparison of H-infinity and mu-synthesis based flow controllers for high-speed networks with multiple time delays
(IEEE, 2001)A flow controller design approach based on mu-synthesis is proposed. The performances of the resulting controllers and the H-infinity controllers designed based on an approach proposed earlier, are compared. -
General orthonormal bases or robust identification in H-infinity

Overlapping decompositions and expansions of Petri nets
(IEEE-Inst Electrical Electronics Engineers Inc, 2002)Overlapping decompositions and expansions are considered to design decentralized controllers for discrete-event systems (DESs) modeled, by Petri nets. The inclusion principle for Petri nets is first defined. It is shown ... -
Controller design to enforce boundedness, liveness and reversibility in Petri nets
(Pergamon-Elsevier Science LTD, 2003)Supervisory controller design to enforce boundedness, reversibility, and liveness in ordinary Petri nets with weighted arcs is considered. Algorithms are presented to design a controller to enforce these properties ... -
Power quality event detection using joint 2D-wavelet subspaces
