This work is the study of tracking control of rigid body in a general way using a geometric approach. To achieve globally valid characteristics, it is necessary to study such a control problem in its own natural nonlinear space using differential geometric properties of the space. By linking the tracking control problem to the problem of stabilization of a single equilibrium of an error dynamics, a tracking controller in the general case of a compact Lie groups has been developed. Then, using Lassale invariance theorem convergence to one of the equilibrium points of error dynamics has been established. Behavior of the system around its equilibrium points is studied by linearizing the system, which proved the almost-global attractiveness of the desired equilibrium. The general control problem studied, in its special case of space of rotation matrices is applied to attitude control of a Quadrotor UAV. Performance of the controller is demonstrated through numerical simulations.

Geometric tracking control of a fully actuated rigid body and applicatin to attitude control of a quadrotor UAV
Bashiri Bargoshadi, Vahid; Kutay, Ali Türker; Department of Aerospace Engineering (2014)

To achieve globally valid characteristics, it is necessary to study such a control problem in its own natural nonlinear space using differential geometric properties of the space.

Numerical simulation of non-reacting turbulent flows over a constant temperature solid surface in regression
Karaeren, Cenker; Albayrak, Kahraman; Department of Mechanical Engineering (2007)
In this study, an attempt is made to obtain convergent and stable solutions of the K-E turbulence model equations for non-reacting turbulent flows over an isothermal solid surface in regression. A physics based mathematical model is used to describe the flow and temperature field over the moving surface. The flow is assumed to be two-dimensional, unsteady, incompressible with boundary layer approximations. Parabolized form of the standard K-E equations is adopted to simulate turbulence in the flow. Regressi...
Implementation of turbulence models on 2d hybrid grids using an explicit/implicit multigrid algorithm
Yılmaz, Ali Emre; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2011)
In this thesis study, implementation, numerical stability and convergence rate issues of turbulence modeling are explored. For this purpose, a one equation turbulence model, Spalart-Allmaras, and a two-equation turbulence model, SST k-w, are adapted to an explicit, cell centered, finite volume method based, structured / hybrid multi grid flow solver, SENSE2D, developed at TUBITAK-SAGE. Governing equations for both the flow and the turbulence are solved in a loosely coupled manner, however, each set of equat...
Nonlinear Structural Coupling: Experimental Application
Kalaycioglu, Taner; Özgüven, Hasan Nevzat (2014-02-06)
In this work, the nonlinear structural modification/coupling technique proposed recently by the authors is applied to a test system in order to study the applicability of the method to real structures. The technique is based on calculating the frequency response functions of a modified system from those of the original system and the dynamic stiffness matrix of the nonlinear modifying part. The modification can also be in the form of coupling a nonlinear system to the original system. The test system used i...
Cyclic behaviour of precast beam-to-column connections: An experimental and numerical investigation
Torra-Bilal, Ines; Mahamid, Mustafa; Baran, Eray (2022-01-01)
The main objective of this study is to examine the behavior of hybrid beam-column connections with numerous detailing methods to be incorporated in precast moment resisting frames under simulate reversed cyclic loading, which will lead to better understanding of their performance and safer seismic applications. To accomplish the research objectives, an integrated experimental and numerical study was conducted. The experimental part consisted of reversed cyclic loading of precast concrete beam-column specime...
