MIL real time simulation of electrical motors
Bartík, Ondřej ; Veselý, Libor (referee) ; Blaha, Petr (advisor)
The goal of this thesis is how to implement the two different types of the electric alternate motors in ZYNQ-7000 device for MIL real-time simulation purposes. The chosen types of motors are BLDC motor and AC induction motor. Mathematics models of these motor, the necessary changes for implementation purposes and the way how the models were implemented in ZYNQ-7000 device are described in this work. Three different experimental MIL simulation, using these motors ae described at the end of this thesis.

Control of ball and plate system
Bednář, Ladislav ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The goal of this work is to design a control algorithm for position controlling of the ball on 2D plate with feedback implemented by camera. Frist part is devoted to the design of steper motor controller, that is controlled by analog inputs. Controller was tuned on CompactRIO platform later replaced with microprocessor by Freescale. PCB design for microprocessor board is included. Next we described controlled system by mathematical model, which we use for PID controller design. Mathematical model is designed in linear form and nonlinear form, which analyze nonlinearity of rolling friction. Image processing with control loop is contained in Matlab-Simulink workspace. At last, laboratory task is designed.

Interconnection of AURIX microcontroller with NVIDIA Jetson platform
Smrčka, Michal ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
Part of this thesis covers the basics of working with NVIDIA Jetson Nano and AURIX Application Kit platforms, namely TC277 TFT and TC224 TFT. It also theoretically analyzes some peripherals of the platforms. These basics are necessary for the following part, which is focused on the implementation of a serial communication interface for data transfer between platforms. The work describes a program implementation of 2 interfaces: SPI and Ethernet MAC. The communication via SPI (or QSPI in the case of AURIX) is supplemented with the use of GPIO pins, in the case of Ethernet the communication is realized at a link layer using Ethernet frames. The connection via SPI is further tested in a specific application when controlling a BLDC motor using TC224 and AURIX eMotor Drive Kit V2.1, where the measured data is sent to the Jetson Nano for real-time processing.

HIL model of electromechanical system
Malík, Lukáš ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
This diploma thesis deals with creation of elektromechanical model in Modelica language which is subsequently imported into LabVIEW environment. The Modelica language, LabVIEW graphical programming tool and Functional Mock-up Interface 2.0 standard are described in the introduction of this thesis. Functional Mock-up Interface is a tool independent standard witch, defines a standardized interface to ModelExchange and Co-simulation of complex system components. The model of electromechanical system was created based on Functional Mock-up Interface standard. Part of the work focuses on the Functional Mock-up Unit storage possibilities and LabVIEW support to import models of this type. The imported model was simulated and tested in this environment. Finally, the instance of Functional Mock-up Unit was connected with LabVIEW FPGA target for the purpose of model HIL simulation on CompactRIO platform.

Aircraft engine voltage regulator
Formánek, Michael ; Bartík, Ondřej (referee) ; Kaczmarczyk, Václav (advisor)
The work deals with the issue of the current solution of on-board network regulation in aircraft using Walter-made Czech engines, especially Walter M137 and M337. The work deals with the style of the currently used solution for operating the generator and the possibilities of its replacement using modern technologies. The design and production of the newly designed device follows. An essential part of the work is also the identification of the system of the original solution and the associated design of a new controller. The work compares the original and proposed solution in several defined points. The following text also includes the certification page of the proposal, financial evaluation and recommendations for further direction.

Parametrization of PID controller on Mitsubishi PLC
Koláčný, Michal ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
The aim of this thesis is to create a demo application for a brief introduction with the components of the PID regulator. The PID regulator is realized by a function block, which is implemented in a Mitsubishi PLC series iQ-F. The controlled variable is the height of the ping pong ball. The ball is kept at the desired height by changing the air flow rate. The change of the air flow is achieved by changing the motor speed. A propeller is mounted on the motor shaft which blows air into the tube. A SHARP GP2Y0A41SK0F optical distance sensor is built into the tube to sense the actual height of the ball. A model of this system is created and simulated in MATLAB program.The current information about the system is displayed on the Mitsubishi GT-2104RTBD operator panel, where it is also possible to change the sizes of individual parameters of the regulator.

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.
