Synchronization of oscillators not sharing a common ground Tuna, Sezai Emre (2023-5-01) Networks of coupled LC oscillators that do not share a common ground node are studied. Both resistive coupling and inductive coupling are considered. For networks under resistive coupling, it is shown that the oscillator-c...
Structural Analysis of Synchronization in Networks of Linear Oscillators Tuna, Sezai Emre (2022-07-01) In undirected networks of identical linear oscillators coupled through dissipative and restorative connectors (e.g., pendulums undergoing small vibrations connected via dampers and springs), the relation between asymptotic...
Harmonic synchronization under all three types of coupling: Position, velocity, and acceleration Tuna, Sezai Emre (2021-08-01) Synchronization of identical harmonic oscillators interconnected via position, velocity, and acceleration couplings is studied. How to construct a complex Laplacian matrix representing the overall coupling is presented. It...
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 ...
