Adaptive control for a class of large scale non-linear systems
(2005)The design of stabilizing controllers for multi-input multi-output (MIMO) non-linear plants with unknown non-linearities is a challenging problem. The inability to identify the non-linearities on-line or off-line accurately ...

Bond graph based modal decomposition of systems with non-proportional damping
(Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Street, Nicosia 1678, CyprusCorrespondence Address: Louca, L.S.Department of Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Street, Nicosia 1678, Cyprusemail: lslouca@ucy.ac.cy, 2012)Modal analysis of lumped parameter and continuous dynamic linear systems is extensively used to study their dynamic behavior and controller design. In both cases, a reduction of the model size that does not degrade accuracy ...

Bounds on the size of minimal nonnegative realizations for discrete-time LTI systems
(1999)Nonnegative linear time-invariant (LTI) state-space models are characterized by the property that their state variables and outputs remain nonnegative whenever the initial state and the inputs are nonnegative. Necessary ...

Control of quantized multi-agent systems with linear nearest neighbor rules: A finite field approach
(2010)We study the problem of controlling a multi-agent system where each agent is only allowed to be in a discrete and finite set of states. Each agent is capable of updating its state based on the states of its neighbors, and ...
