Implementace vybraných řidicích algoritmů pro FPGA / Implementation of selected control algorithms for FPGA

Bradáč, Martin January 2011 (has links)
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.

Experimentální biomechanická protéza ruky / Experimental biomechanical hand prosthesis

Lux, Martin January 2012 (has links)
This masters thesis deals with experimental biomechanical hand prosthesis designing and its realization in shape of prototype. Hand prosthesis sizing corresponds with adult man hand. Prosthesis functionality is selected with respect to search analysis results, to provide sufficient options to grip different objects. Hand design, including technical documentation, is completely made in Autodesk Inventor 2012. Main parts of prototype are made with using rapid - prototyping technologies. Used materials for parts made by this way are ABS plastics and plaster powder. Firgelli linear actuators (product line L) are used as drive for electrical controlled fingers. Prototype control is realized by PCI card and program, which has been written in LabView.

Návrh robotického pracoviště pro zátěžové testování / Design of a Robotic Cell for Load Testing Purposes

Konečný, Tomáš January 2015 (has links)
This thesis is focused on design of a robotic cell for load testing purposes. At the beginning the aim of work is determined by objective testing. Next part is description of a test object, current work station and the present state of work. Further is determined one variant of solutions and are selected elements of the robotic cell. The design of layout follows especially with regards to safety and is processed simplified risk analysis. The second half of the work consists of developing a driverless robot design of the measuring device. The end of thesis is price calculation.

Algoritmy pro stanovení efektivní hodnoty napětí / RMS Value Measurement Algoritihms

Zedník, Josef January 2016 (has links)
This master´s thesis focuses on theoretic analysis selected methods for determination effective value of non-coherent sampled voltage signals. In thesis are described algorithms for calculation effective value in time and frequency domain. One of task this thesis was design methods of program for simulation selected methods of measurement non-coherent sampled voltage signals. This program is realized in developmental environment of LabVIEW and his realization is described in this thesis. User has possibility calculate effective value and bias characteristic depend on selected method and selected input signal. Part of this thesis are simulations, which compares selected methods of calculation effective value.

Optimalizace modelu vodní elektrárny / Optimization model of hydropower plant

Kršiak, Oliver January 2016 (has links)
This diploma thesis deals with the creation measuring instruments and program for controlling model hydropower plant intended for laboratory use. The first step is to improve the mechanical performance of the original model of hydroelectric power. The second step is to select a revive measuring instruments for electric values of the plant. The third step is to create a program for displaying electrical parameters and control the plant. The final step was re-measuring the operating characteristics of the generator model hydropower plant.

SW moduly pro NI VeriStand / SW modules for NI VeriStand

Žlebek, Jan January 2017 (has links)
Thesis is oriented to analysis of existing solutions and making own solutions of SW mo- dules for NI VeriStand. These modules are meant to enable communications with CAN, ARINC429, RS-485, SPI and SDLC buses in scope as defined by Honeywell company. To work on base of existing solutions is highly suitable, and in case of existence of sufficient implementation no additional work is appropriate. Analysis of current state of availa- ble SW resources revealed, that sufficient components for CAN, ARINC429 and RS-485 exist, so I continued to implement only SPI and SDLC. Components are designed as NI VeriStand Custom Devices and have their own FPGA parts.

Automatizované měření charakteristik dvojbranů v DC, AC a časové oblasti / Measurement setup for DC, AC and transient testing of two-ports

Káňa, Vojtěch January 2017 (has links)
This master´s thesis describes about automated measurements of two – ports of frequency, time and DC area. Gradually, there is elaborated several theoretical foundations dealing with this issue. For example, different types of buses, available programs and general theory of two – ports circuits. Also a method for solving and implementing a measuring device for communication between apparatuses and DUT is designed and described. In conclusion, the results and evaluation of measurement are processed.
