Laboratory exercise for a control theory courses
Kozumplík, Miroslav ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This work deals with a design of laboratory tasks and laboratory hardware for laboratory control. Laboratory equipment contains heating element placed in a pipe. Temperature sensors measure the current air temperature in the pipe. The heating element with the temperature sensors are connected to the computer through the DAQ USB-6001. The signal is read by Simulink program that will be used to design controllers for this system.

Restoring of the ventilation shaft generator
Veselý, Libor ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
The subject of this work is the repair of an air-handling unit. Possible causes of the problem are analyzed and multiple solutions are proposed. The first variant considers the refurbishment of the damaged component using thermal spray technology, including the choice of the best method. The second solution proposes the manufacture of a new part using machining in the environment of the company. This process requires an intermediate product to be made, and the choice of the correct machines from what the company has available, choice of the right tools and cutting conditions. The technical-economical evaluation compares the the expenses tied with both of the solutions. The chosen repair solution was used for the repair of the air-handling unit.

Comparison of PID controllers
Prosecký, Jan ; Veselý, Libor (referee) ; Dokoupil, Jakub (advisor)
The work deals with the issue of selecting a suitable discrete PSD controller. The basic types of continuous PID controllers and discrete PSD controllers are shown here. Next, the solution of system identification using Matlab/Ident is described. The tested PSD controllers were a position PSD controller, a PSD controller with differential component filtering and a Beta PSD controller, which was in the settings of the S-PD controller and the PS-D controller. The following methods were used to set the controllers: Ziegler-Nichols, Quadratic integral criterion, experimental settings using the distribution of poles and zeros in the Bode diagram through the Matlab program and the optimal modulus method. Individual controllers are compared by the Matlab/Simulink program in the Automation studio.

Modeling and control of stepper motor in MATLAB/Simulink
Macek, Daniel ; Veselý, Libor (referee) ; Kozovský, Matúš (advisor)
The work deals with describing the types of stepper motors, as a method of their controlling, their potential method of modelling each type of motors. Main purpose was to design a model of stepper motor with controlling in open-loop for modes Full-step, Half-step and Microstepping and controlling in closed-loop. Resultant design model of stepper motor compare with real stepper motor.

Technological process simulation
Dostál, Jiří ; Veselý, Libor (referee) ; Malounek, Petr (advisor)
This paper deals with a design of an inverted pendulum model and its controller in Matlab/Simulink, a conversion of the model and its controller to the ANSI C language and its implementation to B&R PLC's. The source code for B&R PLC's is generated automatically by the B&R Automation Studio Target for Simulink library. The first part deals with the design of a mathematical model of the inverted pendulum and its simulation in Matlab/Simulink, followed by a design of a LQ controller for this model using Matlab functions and a description of the B&R Automation Studio Target for Simulink library. The last part of this paper deals with the implementation of the model and its controller into two separate B&R PLC's, which are networked with the Ethernet Powerlink industrial fieldbus and it also describes visualizations that were designed for operating the system.

Simulation of the Drive with Synchronous Machine and its Evaluation using a Real System
Tkadlec, Josef ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
Práce se zabývá modelováním PMSM, jeho parametry a jejich získáváním. Dále je v práci popsán model měniče beroucí v potaz dead-time efekt. Tyto modely jsou implementovány společně s dalšími bloky v prostředí Matlab/Simulink a dohromady tvoří knihovnu pro vektorové řízení motorů FSL_MC_TOOL. Součástí práce je také měření a identifikace parametrů skutečného PMSM. Dále byly vytvořeny příklady simulací, v nichž je použit motor s těmito parametry a vyhodnocena přesnost simulace. Tímto jsou simulace ověřeny na reálném systému.

Mathematical model of a climatic chamber
Hort, Tomáš ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The objectives of this bachelor thesis are designed and verification matchematical model climatic chamber - incubator. In the beginning, the I2C communication bus is decribed. Then, the humidity and temperature sensors are analysed. Measuring and controling system CompactRio is used for processing data, program Labview is used for programming. Identification of system and designing matchematical model is accomplished in System Identification Toolbox. In the next part, the methods of heat transfer are discussed. The thermal analysis of the system was used to build a physical model in Simulink - Simscape Thermal. The last chapter is focused to the creation of a compact datalogger designed for long-term recording of measurements in an incubator.

Modeling and control of aircraft jet engines
Voda, Tomáš ; Blaha, Petr (referee) ; Veselý, Libor (advisor)
This thesis deals with the description of aircraft engines, their control requirements and control possibilities of these engines. In the practical part, the Jetcat P80-SE engine model was created. This model was then verified against a real engine with measured actual engine speed and temperature. These parameters were then compared with simulated engine speed and temperature. Due to this comparison we can say that it was possible to create a model of the engine that corresponds to the real engine. In addition, the speed controller was designed to meet the control requirements over the speed range. A PI speed controller was designed in different variants, the variants were then compared. Due to the safety limits of the manufacturer were not known, limit values were only implemented to show how the limitation could be implemented.
