Comparison of simple and branched control circuits
Blahút, Lukáš ; Vojáček, Zdeněk (referee) ; Davidová, Olga (advisor)
This bachelor thesis deals with possibilities of improving the accuracy and quality by branching simple control loop. The work contains a description of a simple control loop and the different possibilities of its branching. The conclusion includes a proposal of control parameters for simple and branched control loops with regulator's waveforms simulated in Simulink program.

Motion control during hanged object transportation
Richter, Jan ; Davidová, Olga (referee) ; Němec, Zdeněk (advisor)
The Diploma Thesis focuses on examination of most suitable optionsof movement regulation of pendent object from the perspective of various requirements on the course of the process as such. The environment of Matlab-Simulink was used for the analysis. The first part of the Thesis deals with the creation of the model of the whole system and creation of additional models of systems with similar, highly oscillating behaviour. The central part of the Thesis focuses on the design of suitable methods of movement regulation during translocation of the pendent object, which is tested on a simple model of travelling monkey. Four approaches to the problem solving were chosen: simple regulation by PID regulator, branched regulation, state regulation and predicative regulation. All solving options are being analysed and optimised and their results mutually compared according to requirements defined, such as: speed of the process, fluency of the movement, small pose overshoot or small angle of rope deflection.

Control of higher order plant
Zvara, Pavel ; Janečka, Jan (referee) ; Davidová, Olga (advisor)
This work is dedicated to simplifying transfers of proportional and integral non-oscillatory plant of higher-order. A simplification was done in different ways and designed controller parameters. The desired model method was chosen for adjusting all controllers. It is possible to compare the suitability of the simplification with regard to the requirements of the regulation.

Controllers design for plants with large time constants
Omelka, Vlastimil ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
This bachelor thesis aims to present a design of convenient continuous action controllers for plants. A brief summary of methods of design mostly in use is listed in the work. Selected methods are presented with more detailed description and are applied on four particular systems with different time constants. Furthermore the calculated values are being processed using MATLAB - Simulink program. The final readings are evaluated and compared with respect to the quality and precision of the regulation.

Algebraic methods of control for discrete control circuit design
Jurča, Petr ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
The bachelor essay deals with discreet regulation circuits where it is possible to use either a regulator with fast laid textures or a universal regulator. To propose an optimal regulator it is possible to use various algebraic proceeding methods which polynomial. In case of unidimensional task I converted the synthesis of discreet optimal control to solving inexplicit (Diophantine) polynomial quadratic which is possible to solve by various methods.

Simple and branched control circuits
Holoubek, Lukáš ; Švarc, Ivan (referee) ; Davidová, Olga (advisor)
The goal of this thesis is a theoretical and practical comparison of simple and branched controlled circuits in relation to regulation ‘s quality. Theoretical part describes control, regulation, regulation ‘s circuit, regulator and its parameters setting. There are specific transmissions of the regulated system set on which a step signal response and a fault’s signal pulses are simulated on. Regulation’s quality results are closely analyzed and described using Matlab/Simulink program.

Sample tasks for automation education
Dočekal, Aleš ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
The aim of this bachelor tesis puts mind to the problem of forming combinational and sequential logic circuit tasks. These demonstrational tasks will be used in the educational system for the subject automation. To design the tasks was used the program LOGO!Soft Comfort . Verification of proper running was done by the programmale logic controller LOGO! 0BA5.
