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.

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.

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.

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.

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.

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.

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.
