Multiparameter circulating pump driver
Pazour, Zbyněk ; Frýza, Tomáš (referee) ; Kratochvíl, Tomáš (advisor)
This master’s thesis deals with design of the regulation of a circulating pump in a solar system for heating of supply water and design of the regulator for this system. It describes a fundamental principle and layout of a regulated circuit of a heating system. Description of regulation, basic terms, properties and differences between different types of regulation are described in first part of the master’s project. Especially continuous (PID regulator) and discrete (PSD regulator) regulation are presented. Second part of the master’s project is focused on a conceptual design of the circulating pump regulator. The connection system of each part, selection conditions of components and connection scheme of regulator are described. The third section deals with design of controlling algorithm of the regulator. There is a detailed description of libraries and functions in each chapter which were used in programming of PSD regulator algorithm. The regulated system of a solar collector is described at the end of the work. This system is being developed for real testing and setting of regulator.

Industrial PID controller with autotuning and visualisation
Prudký, Miroslav ; Chomát, Luděk (referee) ; Pivoňka, Petr (advisor)
The objective of the thesis is to create software, which implements industrial PID controller enabling smooth switch-over and automatic tuning of parameters. The next objective is to create visualization for this controller. Whole controller have to be implemented into PLC Power Panel (B&R company). At the beginning of the thesis there is theoretical description of all implemented algorithms (discrete control algorithms derived from PID, smooth switch-over, antiwindup, identification algorithms). In the following there is designed program structure, which is state machine-shaped. All algorithms are implemented in ANSI C at first as s-function for Matlab/Simulink program, which enables to simulate and verify the controller. Implementation of controller into PLC Power Panel through the use of Automation Studio program from B&R company is described in the next part. Visualization is created in the same program. Simulations and verifications on mathematical and physical model demonstrates functionality of implemented algorithms, but also points out some problems associated with the use of identification algorithms in real world (noise, quantization in A/D and D/A converter).

Design and construction of automatic galvanic line
Vondruš, Jiří ; Janda, Marcel (referee) ; Melichar, Petr (advisor)
This thesis deals with the design of automated system of electroplating. The first part is centered on designing the technological process for this electroplating and the setout of operating vats. It also deals with the project of mechanical construction, electrical system, with the computing procedure and the optimum choice of gear for galvanic line model. The work includes the design of a DC motor controller, the computing procedure and the construction of heating element for vats heater simulation. The last part of this thesis offers an insight to the control system and the assembled program. In the addendum, the photo of the realized model, the wiring scheme, and the programme transcript for control galvanic line model can be found.

Natural gas expansion unit
Žáček, Ondřej ; Šnajdárek, Ladislav (referee) ; Pospíšil, Jiří (advisor)
The bachelor thesis "Natural gas expansion unit" relates to the problematics of gas pressure reduction from transport network of NET4GAS to the distribution network of JMP Net s.r.o. The thesis consists of three parts. In the first part the reader is introduced to the methods of natural gas pressure reduction, to the behavior and properties of natural gas and to the problematics of pressure levels of the gas pipelines. The second part describes the important segments of the expansion station in Velké Němčice such as the expansion turbine, cogeneration, regulators etc. The third part contains calculation of the most effective operation of the station.

Implementation and analysis of control circuits in MATLAB/Simulink
Hanuš, Tomáš ; Houška, Pavel (referee) ; Singule, Vladislav (advisor)
The thesis is focused on comparing the characteristics of the most common types of controllers. This comparison is done in MATLAB / Simulink to model the DC motor. First, in the thesis, theoretical description of all structures controllers that are tested. This is specifically the PID controllers, PSD, PI-D, PS-D, S-PD, I-PD, PID filtering of derivative and PSD also with this filtration. Then there is the function given the DC motor and its mathematical description. In the last section of the theoretical part describes the different methods of setting regulators. In conclusion, this thesis compares the structure of individual regulators. There are the results. A comparison of their behavior with position control of DC motor.

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.

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.

Controllers design for plants with small time constants
Rozmahel, Ivan ; Rojka, Aleš (referee) ; Davidová, Olga (advisor)
The main reason of this project is to set up and to propose continous controllers for process with small time responses. The regulated circuits with different type of regulators and its different settings were proposed in this project. These parameters were set up with method synthesis. These calculation were compared and evaculated as regards to control accurancy and quality.
