1. Perera, Sulanie. Comparison of Optimal and Geometric Control Methods for regulation of distributed parameter systems.

Degree: 2013, Texas Tech University

This thesis is concerned with several aspects of set-point control for distributed parameter systems. We first present the geometric design methodology for set-point control. We then demonstrate this methodology for a multi-input multi-output set-point control problem for a two dimensional nonlinear convection-diffusion heat equation. Next we consider the main point of this work, to investigate the relationship between the geometric design method and the classical method of PDE constrained minimization from optimal control. We show that for a linear stationary system the geometric method produces an optimal control gain. Then we consider the special case when the number of control inputs is less than the number of measured outputs, for which we obtain an ``overdetermined system". With fewer control inputs than outputs we do not expect to achieve exact asymptotic tracking so we seek a solution with smallest least-squares error. In this case we employ the Moore-Penrose pseudo-inverse in the geometric design strategy to obtain the smallest least-squares error with smallest possible gain. Two examples are given to demonstrate this method. The first example is a stationary control problem for a Laplace equation and the second example involves temperature control of a two dimensional incompressible Navier-Stokes flow. Advisors/Committee Members: Aulisa, Eugenio (Committee Chair), Gilliam, David S. (Committee Chair), Bornia, Giorgio (committee member).

Subjects/Keywords: Set-point control; Overdetermined system; Pseudo-inverse

2. Kincl, Zdeněk. Metody pro testování analogových obvodů: Methods for testing of analog circuits.

Degree: 2019, Brno University of Technology

The thesis deals with methods for testing of linear analog circuits in the frequency domain. The goal is to develop new efficient methods for automatic test plan generation. To reduce test costs a minimum number of measurements as well as less computational demands are the fundamental aims. The thesis is focused on the multi-frequency parametric fault diagnosis which was fully implemented in the Matlab program. The fundamental problem consists in selection of test frequencies which can reduce the influences of measurement errors and errors caused by tolerances of well-working components. The proposed methods for test frequency selection were statistically verified by the MonteCarlo method. To improve the accuracy and reduce the computational complexity of fault diagnosis, the methods based on least-square techniques and approximate symbolic analysis were presented. Advisors/Committee Members: Kolka, Zdeněk (advisor), Vlček, Čestmír (referee), Husák, Miroslav (referee).
