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.

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.

Laboratory tasks for ball on an inclined plane
Řezáč, Martin ; Graf, Miroslav (referee) ; Blaha, Petr (advisor)
The thesis deals with the identification and control of dynamic systems using LabVIEW graphical programming environment. Cascade form of control with PI and PD controllers has been used for regulation and designed in Matlab. These controllers were then tested on real product. Laboratory exercises with model solutions are also included.

Control of hot air tunnel
Šimurda, Jan ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This bachelor thesis is dealing with the reconstruction of hot-air tunnel model for ma- nagement using CompactRIO system from National Instruments company. For a com- munication with the tunnel has been designed a user interface that guides a user through the system identification and controller design, which is testable as a simulation and then on a real device. The result of this thesis is to create a school task implementing the particular procedures.

Helicopter model control
Štefanisko, Ivan ; Blaha, Petr (referee) ; Pohl, Lukáš (advisor)
In this paper we will introduce the existing model of a helicopter for teaching dynamic systems. Later, we will explore various control options of a model, and design laboratory tasks for the selected subject for bachelor‘s and master‘s study. In becoming acquainted with the model of a helicopter we describe hardware parts and the theoretical mathematical model. We can design controls after we have created a subprograms aimed at raising the rotational angle arms, pulse-width modulation to control the motor speed or creation itself control. The control methods we propose are the Ziegler-Nichols and frequency characteristics. The actual laboratory tasks will be formed with respect to the content of subjects taught bachelor‘s and master‘s study.

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.

Implementation of methods for measurement of rotational speed using cRIO platform
Fábry, Tomáš ; Uher, Miroslav (referee) ; Havlíková, Marie (advisor)
This diploma thesis implements methods for a measurement of rotational speed. It is implemented on the Compact RIO platform from National Instruments. Corresponding SW is implemented using the graphical programming language G in LabView environment. Developed system uses two different sensors – incremental encoder and tacho sensor for measurements of rotational speed. Thesis further analysis and implements a method for an encoder nonlinearity determination and for its on-line correction. For used methods, effects adding errors into the measurements are evaluated and quantified.

Measuring and evaluation with platform CompactRIO and LabVIEW
Kantor, Pavel ; Janda, Marcel (referee) ; Huzlík, Rostislav (advisor)
This bachelor’s thesis deals with design and realization of measuring program for measuring EC motor per development environment LabVIEW. The thesis provides short introduction to the LabVIEW environment, shows potential of FPGA and of its use on the CompactRIO platform. It describes methodology of measurement and mentions application possibilities of this platform to the LabVIEW environment. Further, the thesis deals with sorting types, construction and function of EC motor. It mentions eventual problems, which can appear during the solving of measuring program, describes from basics the creation of the program and explains all function of all program parts.

Using WXT520 meter station for measuring the wind energy
Skalička, Jiří ; Macháček, Jan (referee) ; Šlezingr, Jan (advisor)
This bachelor’s thesis introduces the basics of wind energy. It explains the formation of wind, various types of wind engines, different types of wind power plants (divided by installed capacity), basic methods for wind array determination and wind potential in Czech Republic. Then it turns to Vaisala Weather Transmitter WXT520, which is ideal for measurements in wind energy industries. It explains the transmitter’s basic functions, connection and communication options. Practical part of this thesis is dedicated to realization of measurement using National Instruments CompactRIO platform and LabView development environment. Output of this thesis is a program for long term measurements of meteorological data, analysis and archiving of this data.
