Contributions to the study of a class of optimal control problems on the matrix lie group SO(3)Rodgerson, Joanne Kelly 12 July 2013 (has links)
The purpose of this thesis is to investigate a class of four leftinvariant optimal control problems on the special orthogonal group SO(3). The set of all controlaffine leftinvariant control systems on SO(3) can, without loss, be reduced to a class of four typical controllable leftinvariant control systems on SO(3) . The leftinvariant optimal control problem on SO(3) involves finding a trajectorycontrol pair on SO (3), which minimizes a cost functional, and satisfies the given dynamical constraints and boundary conditions in a fixed time. The problem is lifted to the cotangent bundle T*SO(3) = SO(3) x so (3)* using the optimal Hamiltonian on so(3)*, where the maximum principle yields the optimal control. In a contribution to the study of this class of optimal control problems on SO(3), the extremal equations on so(3)* (ident ified with JR3) are integrated via elliptic functions to obtain explicit expressions for the solution curves in each typical case. The energyCasimir method is used to give sufficient conditions for nonlinear stability of the equilibrium states. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plugin

A study of a class of invariant optimal control problems on the Euclidean group SE(2)Adams, Ross Montague January 2011 (has links)
The aim of this thesis is to study a class of leftinvariant optimal control problems on the matrix Lie group SE(2). We classify, under detached feedback equivalence, all controllable (leftinvariant) control affine systems on SE(2). This result produces six types of control affine systems on SE(2). Hence, we study six associated leftinvariant optimal control problems on SE(2). A leftinvariant optimal control problem consists of minimizing a cost functional over the trajectorycontrol pairs of a leftinvariant control system subject to appropriate boundary conditions. Each control problem is lifted from SE(2) to T*SE(2) ≅ SE(2) x se (2)*and then reduced to a problem on se (2)*. The maximum principle is used to obtain the optimal control and Hamiltonian corresponding to the normal extremals. Then we derive the (reduced) extremal equations on se (2)*. These equations are explicitly integrated by trigonometric and Jacobi elliptic functions. Finally, we fully classify, under Lyapunov stability, the equilibrium states of the normal extremal equations for each of the six types under consideration.

Development of an optimisation approach to Alamouti 4×2 space time block coding firmware.Kambale, Witesyavwirwa Vianney. January 2014 (has links)
M. Tech. Electrical Engineering. / Discusses MIMO systems have been hailed for the benefits of enhancing the reliability of the wireless communication link and increasing of the channel capacity, however the complexity of MIMO encoding and decoding algorithms increases considerably with the number of antennas. This research aims to suggest an optimisation approach to a reduced complexity implementation of the Alamouti 4×2 STBC. This is achieved by considering the FPGA parallelisation of the conditionally optimised ML decoding algorithm. The above problem can be divided into two subproblems. 1. The ML decoding of the Double Alamouti 4×2 STBC has a high computational cost when an exhaustive search is performed on the signal constellation for Mary QAM. 2. Though the conditionally optimised ML decoding leads to less computational complexity compared to the full generic ML detection algorithm, the practical implementation remains unattractive for wireless systems.
