Integral quality criteria of regulation
Gruna, Jiří ; Cejpek, Zdeněk (referee) ; Dosoudilová, Monika (advisor)
This bachelor’s thesis deals with the assessment of the quality of regulation using integral criteria. In the first part we are interested in the basic theory of regulation needed to understand the problem. It includes a description of the control system, differential equations in the theory of transfer function, types of regulators and addresses the question of stability. In the second part the thesis introduces the integral criteria. Using their area, we assess the quality of regulation. For clarity, the criteria are supplemented by examples to show their advantages and disadvantages.

The Importance of Laplace Transform in Regulation Theory
Kovářová, Karolína ; Dobrovský, Ladislav (referee) ; Dosoudilová, Monika (advisor)
This bachelor's thesis deals with the significant role of Laplace transform in regulation theory. The theoretical part is dedicated to the properties of this integral transform and the description of the control system. The usage of Laplace transform in search of process variable, step and impulse function is demonstrated on specific examples of oscillation theory. The final part offers a view on Laplace transform using MATLAB software.

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.

Design of control circuit for towing dynamometer
Rýznar, Jan ; Němec, Zdeněk (referee) ; Cejpek, Zdeněk (advisor)
This bachelor’s thesis is focused on design of a control circuit for a towing dynamometer. In the introductory part of the thesis is a detailed description of the towing dynamometer, including its main parts, which are necessary for proper operation. The next chapter is devoted to creating a dynamic model of an existing prototype using Simscape. Furthermore, based on the conditions from the dynamic model, a control circuit is designed, which is introduced in the form of a program into the control unit of the towing dynamometer. Based on the measured data from the transient responses, the function of the controller is gradually tuned to a satisfactory result. Finally, the function of the control circuit is evaluated and then measures to improve the stability, quality and accuracy of control are proposed.

Control Systems
Vala, Jiří ; Konvalina, Jiří (referee) ; Kunovský, Jiří (advisor)
The MSc Thesis deals with real-time modelling, especially with the control circuits, where we focus on the regulation circuit with auxiliary model of the regulated system. The introduction contains the Theory of Controls and regulation. The work is divided into two basic parts. The first part deals with the problems from the theoretical point of view. The theoretical part is concerned with the general systems. Various definitions of systems, their partition and mathematical methods for their description are mentioned after introducing. A description the regulation circuits, their partition, structures and types follows. There are shown the particular regulators and different types of regulated systems in details. Mathematical methods applied to solve the differential equations that describe the models of the systems are summarized in the second part of the work. The end of this chapter is concerned with the TKSL system. In the practical part I have produced Microsoft Power Point program which summarizes the results of experiments, made in the TKSL and TKSL/C system. The output of simulation was transformed into the graphs in the format of Microsoft Excel. The last part deals with suggestion and implementation simulators of control circuits.

Algebraic criteria for stability of linear systems
Gáčová, Veronika ; Lacko, Branislav (referee) ; Dosoudilová, Monika (advisor)
This bachelor’s thesis deals with stability of linear systems and its assessment using especially algebraic criteria. The theoretical part is dedicated to description of control system, meaning of differential equations in the theory of transfer function and description of stability criteria. The main goal of the thesis is to compare difficulty of use of algebraic and frequency stability criteria on a specific example. In addition to this approach, we will be interested in stability of solution of corresponding homogenous differential equation too. Conclusions will be demonstrated using Matlab software.
