Management theories and their using in practice
Václová, Helena ; Tureckiová, Michaela (advisor) ; Šnýdrová, Ivana (referee)
In my diploma thesis I have described several management theories and concepts used in practice and illustrated them with examples from the practice. The theory does not always coincide fully with the praxis, there are rather some common points. Both the company I write about and its management system are very specific, therefore it is a very interesting example, but not generally predicative. I would be glad if this thesis could also serve as a well- arranged material for the people in our company. In the theoretical part I have treated the management theory first in general and then several particular theories or concepts which I examined more deeply. These are the manager theory, the motivation theory, critical success factors, management by objectives, knowledge management. The empirical part concerns the practical use of these theories the company of my interest. The whole thesis is thematically wide, but the extent is limited here. Therefore it does not contain whole descriptions of the theories, but rather insights and some chosen elements. Also the empirical part does not fully examine the function system of the company and the work in it, but chooses the elements corresponding with the theoretical concepts described instead.

Aircraft Modelling - The Kinematics and Dynamics of Aircraft Motion
Kutal, Jiří ; Kaluža, Vlastimil (referee) ; Kunovský, Jiří (advisor)
This bachelor's thesis is focused on general aircraft motion. Main terms connected to modelling continous systems, principles of control theory, linear systems, feedback systems and basic types of regulators are analyzed in the first part of the thesis. Second part mentions mathematical basics connected to modelling, mainly focused on differential equations and Taylor series. Reader can also find out about A/D and D/A convertors. The last part of this bachelor's thesis is dedicated to aircraft motion and the simulation of it's kinetic equations in TKSL program.

Real Time Dynamic System Control
Adamík, Pavel ; Kaluža, Vlastimil (referee) ; Kunovský, Jiří (advisor)
This thesis focuses on the methodology of controlling dynamic systems in real time. It contents a review of the control theory basis and the elementary base of regulators construction. Then the list of matemathic formulaes follows as well as the math basis for the system simulations using a difeerential count and the problem of difeerential equations solving. Furthermore, there is a systematic approach to the design of general regulator enclosed, using modern simulation techniques. After the results confirmation in the Matlab system, the problematics of transport delay & quantization modelling follow.

Control Theory of robotic snakes with more than three links
Tejkal, Martin ; Návrat, Aleš (referee) ; Hrdina, Jaroslav (advisor)
The subject of this Bachelor's thesis is control theory of mechanism that simulates snake's movement. From a viewpoint of control theory the robot is classified as nonholonomic system, controllability of which is determined by vector fields. Based on nonholomic constrain a set of input vector fields is obtained from a system of nonholonomic equations. The other vector fields that are necessary for controllability of the system are derived from the set of input vector fields by application of Lie bracket operation on two input fields. This set of vector fields is further analysed in particular points of the configuration space. Finally we discuss changes that need to be done in order to describe a mechanism created by adding one, or more new links.

The solving of ordinary differential equations by means of the Laplace transform method
Klimeš, Lubomír ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
The Laplace transform is a very powerful mathematical tool for solving of ordinary linear differential equations with constant coefficients. Its usage is wide - it can be applied to first order and also to higher order equations, it is very convenient for solving of differential equations with several forcing terms (including noncontinuous terms) and of course, it can be used for solving of systems of ordinary differential equations. The Laplace transform plays the key role in control theory, where the transformation of the differential equation of the control system enables to analyse the behavior of this system, e. g. its reaction to input values. Our aim was to present essentials of the Laplace transform theory and demonstrate this strong mathematical tool in the solving of concrete problems, including the usage of the software Maple.
