Aplikace posilovaného učení v řízení Smart Home
Biel, Gabriel ; Zbořil, František (referee) ; Janoušek, Vladimír (advisor)
Táto práca skúma, ako môže strojové učenie zlepšiť riadenie inteligentných domácností s dôrazom na optimalizáciu riadenia teploty a zvýšenie energetickej účinnosti. Konkrétne sa porovnávajú dva pokročilé algoritmy posilňovaného učenia, Deep Q-Learning (DQL) a Proximal Policy Optimization (PPO). Tieto modely sú testované v simulovanom prostredí, ktoré napodobňuje reálne podmienky, aby sa zhodnotila ich schopnosť prispôsobiť sa správaniam užívateľov a zmenám v prostredí. Ukázalo sa, že model PPO je obzvlášť účinný vďaka svojej stabilite a schopnosti predpovedať návrat obyvateľov. Tento výskum ponúka cenné poznatky o praktických aplikáciách AI technológií v inteligentných domácnostiach.

Low-cost demonstrators for automatic control methods
Malypetr, Matěj ; Kozovský, Matúš (referee) ; Blaha, Petr (advisor)
This work describes the design and subsequent implementation of two tasks for the demonstration of automatic control using an Arduino development board. The control circuit consists of a physical systemsystém with attached actuator, sensor for the measurement of the system’s output and Arduino board as a control unit with automatic feedback controller of PID type. For both demonstrators, parametric model is obtained from measured data using system identification and output filter is designed and implemented. The controller is designed in the environment of MATLAB® Simulink. Simulink support package for Arduino addon enables to automaticaly compile generated code, to program the Arduino board through USB cable and to launch this program in real-time. It is also possible to monitor and calibrate the constants directly through the Simulink scheme.

Control and regulation of the temperature of the drug transport box
Maťašová, Daniela ; Králík, Martin (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the solution of drug transport in a transport box over longer distances. The work also deals with sensors for temperature measurement and methods of its control and regulation. The essence is the design, implementation and verification of the functionality of the transport device, which allows the display of continuous information about the state of the temperature inside the transport box. Temperature control is powered from the car’s on-board network and temperature sensing is powered independently. The transport device allows the setting of the limit temperature up to 35 °C, while exceeding it is indicated by an acoustic and visual alarm. The transport box, which is the result of the work, allows the transport of drugs, and ultimately meets all the requirements of the assignment.

Laboratory device with temperature control
Telecký, Jakub ; Škrabánek, Pavel (referee) ; Němec, Zdeněk (advisor)
This work deals with regulation and procedures that can be used for this. The theoretical part therefore presents the basic concepts of automation and controllers. The main part is the practical part. The purchased system consists of a regulated system, which must be set up correctly. Using system identification and known procedures, sample examples of how to best set the controller are compiled. The result is a sample laboratory task that automation students can try and gain experience with methods of setting up the controller.

Temperature control
Soviš, Jiří ; Glos, Jan (referee) ; Richter, Miloslav (advisor)
The thesis deals with the issue of temperature control by means of an uncontrolled source of waste heat in a closed room. The main purpose of this thesis is to get acquainted with problematics and technology used in the field of HVAC. Part of the thesis is a solution design of temperature control in which the heat loss from the compressor is used to heat the compressor room and as a supplementary heat source to the production hall to reduce costs. As part of the algorithm solution, was created a temperature model, developed in Matlab / Simulink, which was used to design a PI controller using integral quality control criterion ITAE and Nelder-Mead simplex.

Injection moulding machine prototype
Cikryt, Adam ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This work deals with the design of a prototype injection molding machine for the company Elzaco s.r.o. The work includes theoretical analysis which breaks down injection molding machine into individual components and describes their functionality and their important parameters. Based on the analysis and determination of critical parameters of the injection molding machine, a detailed model of the injection molding machine is created. There are also requirements for electrical components such as motors, power supplies, heaters, temperature sensors, control electronics. The method of controlling such a machine is also discussed.

Data collection from sensor units
Frkal, Pavel ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This thesis deals with data collection from sensor units connected via 6LoWPAN standard (IEEE 802.15.4 standard), which uses simplified IPv6 protocol on the network layer. Featuring optimization makes this solution suitable for use in systems powered with chemical power supplies with a very low current consumption of both the sensor units and the control units. The thesis focuses on collecting data from sensor units that communicate on a star topology basis but it's also discussed possible usage of general topology, the end-station in such case works as active repeater and thus extend sensor network coverage without need of additional devices for wireless frames repeating or forwarding. It evaluates the realization of sensor networks created by both the actual data collection as well as specific technical parameters of used sensor boards. The practical part contains a specific application for gathering data from sensors present on the units and storing them in a relational database MySQL.
