Synchronization of linear oscillators coupled through a dynamic network with interior nodes
Tuna, Sezai Emre (Elsevier BV, 2020-07-01)
Synchronization is studied in an array of identical linear oscillators of arbitrary order, coupled through a dynamic network comprising dissipative connectors (e.g., dampers) and restorative connectors (e.g., springs). The...
Synchronization of linear systems via relative actuation
Tuna, Sezai Emre (Elsevier BV, 2019-12-01)
Synchronization in networks of discrete-time linear time-invariant systems is considered under relative actuation. Neither input nor output matrices are assumed to be commensurable. A distributed algorithm that ensures syn...
Synchronization of small oscillations
Tuna, Sezai Emre (Elsevier BV, 2019-09-01)
Synchronization is studied in an array of identical oscillators undergoing small vibrations. The overall coupling is described by a pair of matrix-weighted Laplacian matrices; one representing the dissipative, the other th...
Observability Through a Matrix-Weighted Graph
Tuna, Sezai Emre (Institute of Electrical and Electronics Engineers (IEEE), 2018-07-01)
Observability of an array of identical linear time-invariant systems with incommensurable output matrices is studied, where an array is called observable when identically zero relative outputs imply synchronized solutions ...
Synchronization of harmonic oscillators under restorative coupling with applications in electrical networks
Tuna, Sezai Emre (2017-01-01)
The role of restorative coupling on synchronization of coupled identical harmonic oscillators is studied. Necessary and sufficient conditions, under which the individual systems' solutions converge to a common trajectory, ...
Synchronization under matrix-weighted Laplacian
Tuna, Sezai Emre (Elsevier BV, 2016-11-01)
Synchronization in a group of linear time-invariant systems is studied where the coupling between each pair of systems is characterized by a different output matrix. Simple methods are proposed to generate a (separate) lin...
A dual pair of optimization-based formulations for estimation and control
Tuna, Sezai Emre (2015-01-01)
A finite-horizon optimal estimation problem for discrete-time linear systems is formulated and solved. The formulation is a natural extension of that which yields a deadbeat observer. The resultant observer is the dual of ...
Deadbeat Observer: Construction via Sets
Tuna, Sezai Emre (2012-09-01)
A geometric generalization of discrete-time linear deadbeat observer is presented. The proposed method to generate a deadbeat observer for a given nonlinear system is constructive and makes use of sets that can be computed...
Synchronization analysis of coupled Lienard-type oscillators by averaging
Tuna, Sezai Emre (2012-08-01)
Sufficient conditions for the synchronization of coupled Lienard-type oscillators are investigated via averaging technique. The coupling considered here is fixed, nonsymmetric, and nonlinear. Under the assumption that the ...
Sufficient Conditions on Observability Grammian for Synchronization in Arrays of Coupled Linear Time-Varying Systems
Tuna, Sezai Emre (2010-11-01)
Synchronizability of stable, output-coupled, identical, linear time-varying systems is studied. It is shown that if the observability grammian satisfies a persistence of excitation condition, then there exists a bounded, l...
