Application for Statistical Analysis of ICS Communication
Chimenti, Andrea ; Bartík, Vladimír (referee) ; Burgetová, Ivana (advisor)
This work aims to present the design and implementation of an application for statistical analysis of network traffic in ICS (Industrial Control Systems) communication. In the first place, the work presents Industrial Control Systems and some of their most common protocols. The protocol IEC 104 is described in more detail. This is followed by an introduction to the basic methods of descriptive statistics, that can be used to analyze industrial communication. For this purpose, several CSV datasets, that capture fragments of industrial communication, have been used. These datasets are used to show how some of the previously described statistical methods can be used. The work then describes the implementation of an application, which allows to analyze the datasets and obtain various statistics and a visual representation of the data. The main objective of the application is to make it easier for the user to find stable characteristics that can be used for anomaly and attack detection. Finally, the benefits that the application brings are demonstrated on a set of datasets containing different types of attacks.

Application for the HAWK regulator
Kvasnička, Petr ; Štohl, Radek (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis deals with the issue of intelligent buildings management and practical use of the control system HAWK from company Honeywell. The thesis describes the basic problem of intelligent building management, exactly why they created and how it is possible to implement building automation, including a listing of available equipment that can be used in these systems. The thesis also discusses one of the systems that can be used for building control. The control system is called HAWK and thesis describes the programming environment and connectable peripherals. For a given control system is formed in the scrubbing practical demonstration device wind tunnel, which is shown using the work of the control system.

Simulation-Based Development of Heating Control System
Tomeček, Jan ; Rozman, Jaroslav (referee) ; Janoušek, Vladimír (advisor)
This thesis is about optimalization of boiler heating from external sources. I have created a simulation model of Heating Control System. Subsequently, using a simulation model, I proposed possible optimizations for water heating control. The used optimization method was deep Q-learning. The result of this work shows the use of simulation for the development and optimalization of control systems.

Machining on a CNC machine including automatic measurement
Kubín, David ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The topic of the bachelor thesis is the analysis and integration of the measuring cycle into the machining process on a CNC machine. The topic is dealt with in two parts, theoretical and practical. The theoretical part briefly discusses the history of NC/CNC machines, including the basic control modes of NC/CNC machines and the structure of the NC programme. Furthermore, the control systems produced by renowned companies available on the Czech market are presented. Besides other facts, measuring cycles in control systems and their examples are also mentioned in this part. The practical part of the bachelor’s thesis is focused on the creation of a suitable illustrative component, the subsequent compilation of operational data and documents into the technological preparation of the production. The production of the component and its subsequent measurements are based on these data. The production process ends with the evalution of the information obtained.

ABB RobotStudio - sample control program for stationary robot
Machala, Jan ; Lacko, Branislav (referee) ; Lang, Stanislav (advisor)
The goal of this bachelor thesis is to create sample control program executing sequence of robot movements and then its implementation on real robot IRB 120. For communication between robot and PLC was used program created in integrated development environment Microsoft Visual Studio. In the introduction are briefly described history of robotics and categories of robots. In the following chapters are described company ABB Group, its products and company B&R Automation and its products focused on control systems. Next chapters describe the solution of the given laboratory task and briefly explain settings of the individual programs. The thesis attachment contains video of the working project tested on real robot.

Vernet Behringer tools for CNC programming
Mana, Marek ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
The master’s thesis is focused on the possibilities of machining lines of the company Vernet – Behringer. The theoretical part is a brief inclusion of the control system ProNC2 between selected commercially available control systems and are compared ways of programming CNC machine tools. On the machine tool of company Vernet – Behringer are processed mainly thin-walled components, that is why is part of the work focuses on the issue of machining thin-walled parts, the distribution of deflection tools and machined parts. The next part of thesis deals with the design and processing of technical documentation for the machined model part. The practical part deals with the possibilities of the machine and method of programming the control system ProNC2. Programming and practical production on machine were proceeded in company SSI Schäfer s.r.o. The work is focused on practical verification of the production process using simulation and production itself. Finally, it was performed technical - economic evaluation of production.

Generic Flow Analysis in Computer Networks
Jančová, Markéta ; Holkovič, Martin (referee) ; Kolář, Dušan (advisor)
Tato práce se zabývá problematikou popisu síťového provozu pomocí automaticky vytvořeného modelu komunikace. Hlavním zaměřením jsou komunikace v řídicích systémech , které využívají speciální protokoly, jako je například IEC 60870-5-104 . V této práci představujeme metodu charakteristiky síťového provozu z pohledu obsahu komunikace i chování v čase. Tato metoda k popisu využívá deterministické konečné automaty , prefixové stromy a analýzu opakovatelnosti. Ve druhé části této diplomové práce se zaměřujeme na implementaci programu, který je schopný na základě takového modelu komunikace verifikovat síťový provoz v reálném čase.

Dynamic Software Architectures for Distributed Embedded Control Systems
Richta, Tomáš ; Kavička, Antonín (referee) ; Sawa, Zdeněk (referee) ; Janoušek, Vladimír (advisor)
Tato prace se zabyva dynamickou rekonfigurovatelnosti distribuovanych ridicich systemu. Vzhledem k charakteristice techto systemu je pro definici jejich behu pouzit formalismus Petriho siti. Tyto jsou transformovany do proveditelne podoby a nasledne pak interpretovany specializovanym software nainstalovanym na jednotlivych uzlech systemu. Diky vlastnostem pouziteho formalismu je mozne jednotlive casti systemu nahrazovat novymi variantami. Stejne tak je mozne generovat formalni specifikace dilcich casti systemu z abstraktnejsich workflow modelu a popisu ve forme domenove specifickych jazyku.
