Solution of Continuous Systems by Evolutionary Computational Techniques
Lang, Stanislav ; Šeda, Miloš (referee) ; Olehla, Miroslav (referee) ; Matoušek, Radomil (advisor)
The thesis deals the issue of solution of continuous systems by evolutionary computational techniques. Evolutionary computing techniques fall into the field of softcomputing, an advanced metaheuristics optimization that is becoming more and more a method of solving complicated optimization problems with the gradual increase in computing performance of computers. The solution of continuous systems, or the synthesis of continuous control circuits, is one of the areas where these advanced algorithms find their application. When dealing with continuous systems we will focus on regulatory issues. Evolutionary computing can then become a tool not only for optimization of controller parameters but also to design its structure. Various algorithms (genetic algorithm, differential evolution, etc.) can be used to optimize the parameters of the controller, for the design of the controller structurewe usually encounter so called grammatical evolution. However, the use of grammatical evolution is not necessary if appropriate coding is used, as suggested in the presented thesis. The thesis presents a method of designing the structure and parameters of a general linear controller using the genetic algorithm. A general linear regulator is known also as so called polynomial controller, if we encounter the polynomial theory of control. The method of encoding the description of the general linear controller into the genetic chain is crucial, it determines a set of algorithms that are usable for optimization and influence the efficiency of the calculations. Described coding, effective EVT implementation, including multi-criteria optimization, is a key benefit of this work.

Modelling and control design of mechatronics systems on state-space
Ertl, Lukáš ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This work is concerned with modeling of simple mechatronic’s systems in state space and with designing their controls. In work is described a method for constructing the state model of direct current motor with programs MATLAB/SIMULINK and NI LabVIEW. There is designed the control for realized model and this control is verified in simulation. Later are model and its control, verified on real system.

Implementation of control a DC motors
Rozkošný, Miroslav ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
The bacheleor thesis deals with the basic classification of DC electromotors and with the principles of their operation. Another part of the thesis describes ways of measuring current and position. Consequently, it describes basic ways of regulation which are then realised with the help of the developing environment NI LabVIEW and experimentally verified. The results of individual experiments with different types of regulators are compared and analysed.

Claw-pole automotive alternator design.
Szekeres, Vojtech ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The thesis deals with the alternators used in passenger cars, their desing, function and typical behaviours and characteristics and design. Alternators are specific with the trapezoidal shape of rotor poles, which produce a waveform similar to a square wave instead of a sinusoid. This is more desirable for simple rectification to direct current, which is used in the electrical distribution system of automobiles. Because of the shape of the poles, these alternators are also called the claw-pole. The design itself consists of creating an alternator in Ansys Maxwell software in compliance with real measured alternator. The results are compared numerically and also graphically.

Design of supply source with several outputs
Lačný, Radek ; Lattenberg, Ivo (referee) ; Novotný, Vít (advisor)
The main objective of this work is a design of supply power source with several outputs for a telephone subscriber module. This module consists of two parts. First one is a control block containing a processor and auxiliary circuits, which requires voltage +3.3 V and +5 V. The second part is a board with cards, which provides dual telephone line feeding each and the board requires voltage in the -24 and -75 V. Bachelor's thesis contains a brief description of the basic types of convertors used in switched power sources, then the design of required power supply for the subscriber module together with the draft printed circuits and also the alternative power sources based on commercial products available on the Czech market. The resulting electrical scheme of power supply, including the printed circuits board schemes are presented in the Annex of the thesis.

Small Control Sysrtem with Ethernet Bus
Liška, Radovan ; Kaňa, Zdeněk (referee) ; Bradáč, Zdeněk (advisor)
The thesis is concerned by complex proposal and by solution of PCB (printed circuit board) for small control system with ethernet connection. This thesis is solving proposal for supply circuit issue, which means galvanic separation circuit, regulation and stabilization of voltage. For communication sensing units or other units with automatic controller is used industrial communication with RS232 and RS485 interface. Automatic controller gain information from feed system by analog and digital inputs. Activator is controlled by analog or digital outputs from microcontroller.
