Real Time operating system in LabVIEW - LabWINDOWS/CVI
Povolný, Petr ; Beneš, Petr (referee) ; Čejka, Miloslav (advisor)
The aim of this theses is to make user acquinted with programming of real time applications in LabVIEW and LabWINDOWS/CVI environment. The introduction outlines basic properties and parametres of operating systems. Key requirements of real time operating systems are discussed here. Their basic concept is described, focusing on VxWorks operating system and comparison with deterministic properties of common MS Windows operating system. In the second part, there is a brief specification of LabVIEW and LabWINDOWS/CVI environment and a description of real time applications built up in these environments. The final part of this theses proposes a system for analog data acquisition for checking on deterministic properties of real time application and applications built up on MS Windows.

Mechanical manipulator controlled from the cRIO platform
Karásek, David ; Šedivá, Soňa (referee) ; Havránek, Zdeněk (advisor)
This bachelor thesis is about designing and creating control software for 2 D mechanical manipulator. This device consists two translational actuators and one rotational actuator. At theoretical part author discuss possible hardware solutions and talks about basic terms used in practical part. Practical part is about designing main control application. Final program is fully functional, at the end of this thesis the author suggests some improvements which could be done to the program.

Control of BLDC motor at LabVIEW
Bulín, Tomáš ; Pazdera, Ivo (referee) ; Huzlík, Rostislav (advisor)
The aim of my thesis is to become familiar with the program LabVIEW, CompactRIO platform and features it offers to control BLDC engine. A comprehensive program from National Instruments LabVIEW is used in a wide range of industrial applications ranging from measurement of electrical signals, data collection, automation of the measurement, to the control of various engines and applications. In addition, the program renews itself every year and as each new version comes with many new enhancements that improve its functionality even more. It use to actual control the CompactRIO platform, in which is loaded a program created to control the application. The main advantage is that the user has the option to modify the program according to their needs and he don’t have to send his applications to the manufacturer for each change in the source code of control program. CompactRIO caters to not only control your own applications, but is also able to measure the values needed to run the program.

Remote device control over TCP/IP
Skalník, Marek ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This work describes an application of the ATMEL micro-controller AT91SAM7X512, with ARM architecture, for use with ethernet interface. A part of the work gives attention to the development environment Eclipse used for design and compilation of applications and also to the SAM-BA software by ATMEL utilized for upload of the particular application into the micro-controller memory. Next part describes possible usage of the Real-time operation system (RTOS) in embedded systems and shows a demo application of a webserver with an option to set IP addresses.

Real-time Control of Ball on Wheel Model
Krejčí, Roman ; Otava, Lukáš (referee) ; Hynčica, Ondřej (advisor)
This diploma thesis deals with control the Ball on the wheel system in real time. In the first part there is made mathematical model of system, which is described by state equations. Then the laboratory model of Ball on the wheel system and its parts are described. The laboratory model consists servo drive, servo amplifier, microcontroller with real-time operating system and distance sensors. In the practical part of the thesis there is designed control of system by linear quadratic regulator and its implementation with control peripherals into microcontroller with real-time operating system. Ball on the wheel system is controlled by microcontroller, which sends a commands to servo amplifier by CAN bus.

6 Axis Manipulator Control
Semrád, Michal ; Chromý, Adam (referee) ; Hynčica, Ondřej (advisor)
This master thesis discusses about designing and realization of a control system for a 6-axis robotic arm. The controlling system consist in a microcontroller LPC1756 with its firmware implemented under the Real-time operating system FreeRTOS and GUI application, running on a PC. The Microcontroller communicates with the PC through a serial line via SLIP protocol. Theoretically, it will deal with an explanation of the important terms, and describes the used robotic arm and its controlling unit. The practical part describes kinematics problems solving, firmware’s realization and GUI application.

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.

Self-service station for charging of electric automobiles
Kubizňák, Jan ; Fojtík, Pavel (referee) ; Kučera, Pavel (advisor)
The subject of this diploma thesis is a creation of SW for the self-service charging station of ELNICO Ltd. company. The work consists of two main parts. The first part contains an overview of general charging stations for electro cars at current market. After this the prototype of the ELNICO system is described. It's main components and the control system realized by the development kit DK-LM3S9B96 are characterized here. The real-time operating system FreeRTOS, that is used by the kit, is also specified. The second part of the document deals with the SW design and realization. The thesis describes the structure and the main modules of the program. The functionality is then demonstrated by photos of running application.
