Laboratory wind turbine control system
Borski, Roman ; Bok, Jaromír (referee) ; Šlezingr, Jan (advisor)
This thesis is about creating measure and control system for wind turbine DS 300. This system purpose is data collection of wind turbine, especially measurement of supplied power and their archivation. Next is to expend control functions, which are supported by transducer, that is provided by the wind turbine manufacturer, especially for remote shut-down function of wind turbine. Created control system is based on CompactRIO platform, whose software is created in LabVIEW.

Implementation of selected control algorithms for FPGA
Bradáč, Martin ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
A real-time computer cRIO-9073 supplied by National Instruments, together with the software tool LabVIEW is a versatile system used in many fields, for both research and practical tasks. This thesis deals with the possibilities of the system. It is aimed primarily at performance testing, identifying potential limitations and showing its practical use. The whole system has undergone testing through the use of programs covering the wide spectrum of utilisation. cRIO also allows the use of other software tools in its programming. This thesis explores the options of using Matlab/Simulink from MathWorks and the generation of VHDL code using a product of Xilinx. The aim is to compare the demands on the resources consumed, by the Field-programmable gate array (FPGA) in cRIO as well as the CPU load running the Real-time process.

User-defined Measurement Modules for cRIO
Pivnička, Martin ; Vágner, Martin (referee) ; Havránek, Zdeněk (advisor)
This thesis describes design and manufacture of measuring and communication modules for CompactRIO platform. In the first section is described platform from National Instrument suitable for measurement and control technology. There is written more fact about CompactRIO. The second part is focused on description of the hardware requirements needed to construct the module, communication and working modes. The third part describes information about support programs. At the end of third part is describes practical application of input digital card. Next section consists of practical proposal modules (input / output analog module, GPS modulu) and achievements.

Device for diagnostic of induction machine
Buln, Tom ; Janda, Marcel (referee) ; Huzlk, Rostislav (advisor)
The aim of the thesis is to study the problems of induction motors, which belong among the most widespread and used machines. Due to their expansion, it is advisable to start the fault monitoring to prevent any more damage and losses. It can be used for condition monitoring different types of methods, which are variety technically and costly demanding to implement. It is used the method of measurement using stator currents in this thesis, because these currents are already monitored and it is easy to create devices for a more detailed analysis. The whole monitoring is carried out using products from National Instruments. The program of monitoring is created in graphical setting of LabVIEW. The analysis is conducted by calculating the Fast Fourier transform of the time signal. The result is the frequency spectrum, which contains frequency peaks and some of these peaks represent failure. The test data are collected with a DAQ device and then the same data are used for creating a methodology for evaluating online analysis and it is subsequently implemented into CompactRIO.

Frequency measurement
Milota, Martin ; Havránek, Zdeněk (referee) ; Čejka, Miloslav (advisor)
The theme of this thesis is presentation of the CompactRIO platform by National Instruments with its range of hardware and the possibility of using this platform for the frequency measurement of analog signals. The result of this thesis is software equipment for this device focusing on the frequency measurement of analog signals and experimental verification of posibilities of a specific configuration of this platform in the range of measurable frequencies.

Features real-time operating system for LabVIEW
Válek, Petr ; Beneš, Petr (referee) ; Čejka, Miloslav (advisor)
This thesis deals with certain properties of real time operating systems (RTOS) Ardence PharLap ETS, WindRiver VxWorks and LabVIEW RT module. Three methodologies of RTOS quality comparison are proposed, two of which are practically tested with described experiments on CompactRIO hardware from NI. Furthermore, there is explained need for RTOS usage and experimental comparison of jitter error influence on total harmonic distortion THD defined by two definitions.

Control system design for robotic manipulator
Křivánek, Štěpán ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
Main goal of this thesis is to design and realize software for controlling planar robotic manipulator “Mini-swing”. At the beginning, thesis describes general issues of this problem. Research part deals with dividing manipulators in groups by their kinematic configuration. Next part merely outlines usage of National Instruments module “Robotics”. “Mini-swing” manipulator and its kinematic are described in the following part. Design and realization of software for controlling Mini-swing’s ending effector are parsed in next part and at the very end of thesis you can find summarization of accomplished results.

Control of three-axis Cartesian manipulator
Drha, Štěpán ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
The bachelor thesis deals with the proposal and realisation of the control system of the universal Cartesian manipulator. The aim of the thesis is to create a functional control system of the manipulator with the usage of available hardware and software modules. The introduction of the work summarizes general issues of the Cartesian manipulators controlling. The following chapter occupies with the selection of the individual software and hardware modules of the control system. Based on these modules, the control system of the manipulator is designed and realised. The conclusion of the work evaluates the results and it proposes possible improvements for this application.
