1. Daniel, Martin. Optimalizace v řízení dynamických systémů: Optimization in control systems.

Degree: 2019, Brno University of Technology

Master’s thesis deals with using a linear matrix inequality (LMI) in control of a dynamic systems. We can define a stability of a dynamic system with a LMI. We can use a LMI for research if the poles of a system are in a given regions in the left half-plane of the complex plane with a LMI or we can use a LMI for a state feedback control. In the work we describe a desing of a controller minimizing a norm from an input to an output of the system. There is also a desing of a LQ controller with a LMI. In the end of the work, there are two examples of a design a LQ controller, which minimize the norm from the input to the output of the system and moves a poles of a dynamic system in a given regions in the complex plane, with the LMI. We use a LMI for a design a continuos LQ controller in the first example. In the second example we use a LMI for a design a discrete LQ controller.

2. Piddubna, Ganna Konstantinivna. Lineární maticové diferenciální rovnice se zpožděním: Linear Matrix Differential Equation with Delay.

Degree: 2019, Brno University of Technology

This work is devoted to computing the solution, stability of the solution and controllability of respective system of linear matrix differential equation with delay x'(t)=A0x(t)+A1 x(t-tau), where A0, A1 are constant matrices and tau>0 is the constant delay. To solve this equation, the "step by step" method was used. The solution was found in recurrent form and in general form. Stability and the asymptotic stability of the solution of the equation was investigated. Conditions for stability were defined. The Lyapunov’s functional theory is basic for the investigation. Necessary and sufficient condition for controllability in same matrices case was defined and the control was built. Sufficient conditions for controllability in communicative matrices case and general case were defined and controls were built. All results were illustrated with non-trivial examples.

3. Baštincová, Alena. Odhady řešení diferenciálních systémů se zpožděným argumentem neutrálního typu: Estimation of Solutions of Differential Systems with Delayed Argument of Neutral Type.

Degree: 2019, Brno University of Technology

This dissertation discusses the solutions to the differential equation and to systems of differential equations. The main attention is paid to study of asymptotical properties of equations with delay and systems of equations with delay. In the first chapter are given physical and technical examples described by differential equations with delay and their systems. The classification of equations with delay is given and basic notions of theory of stability are formulated (mainly with the emphasis on the Lyapunov second method). In the second chapter estimates of solutions of equations of neutral type are studied. The third chapter deals with systems of differential equations of neutral type. Asymptotic estimates for solutions and their derivatives are proved. At the end of the chapter examples and comparisons of our results and of other authors are given. The calculation were performed with the MATLAB software. Last, the fourth chapter deals with asymptotical properties of systems having a special type of nonlinearities, so called ``sector nonlinearities''. Properties and estimations of solutions and derivatives are derived. The basic tools used in the dissertation are the Lyapunov second method and functionals of Lyapunov-Krasovskii type. Advisors/Committee Members: Diblík, Josef (advisor), Růžičková, Miroslava (referee), Dzhalladova,, Irada (referee).
