Control of a rotational inverted pendulum
Bednář, Ladislav ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
The goal of this work is modelling and design of an inverted pendulum prototype. The work presents a mathematical model of a rotary pendulum, modelling of a BLDC motors and also a 3D model of the pendulum prototype is present. The work mentions design of the state space controller and swing up control of the inverted pendulum. Dynamics obtained from the mathematical model is used to create a 3D dynamic model of a pendulum, with the use of the Simscape toolbox. The work deals with control of a BLDC motors with use of vector control. The algorithm is implemented on the CompactRIO platform. Later, hardware is developed, containing STMicroelectronis microcontroller, capable of replacing the CompactRIO platform.

Mathematical model of a climatic chamber
Hort, Tomáš ; Bartík, Ondřej (referee) ; Veselý, Libor (advisor)
The objectives of this bachelor thesis are designed and verification matchematical model climatic chamber - incubator. In the beginning, the I2C communication bus is decribed. Then, the humidity and temperature sensors are analysed. Measuring and controling system CompactRio is used for processing data, program Labview is used for programming. Identification of system and designing matchematical model is accomplished in System Identification Toolbox. In the next part, the methods of heat transfer are discussed. The thermal analysis of the system was used to build a physical model in Simulink - Simscape Thermal. The last chapter is focused to the creation of a compact datalogger designed for long-term recording of measurements in an incubator.

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.

Measurement System For Determining Forces Acting On Loose Concrete Roof Paver
Mancl, Vlastimil
This paper introduces the topic of measuring the wind-induced forces on a concrete roof pavers. It describes the creation of a system, allowing such measurements and it also proposes two methods. First discussed method is measuring differential pressure. The second is measuring the weight of a roof paver. This article proved, that those methods can give meaningful results and that the future research should continue to use and improve this measurement system.

Compactrio Module For Servomotor Control
Macek, Daniel
The paper deals with the design of a user card for the National Instruments CompactRIO platform. The proposed module allows control of servomotors such as BLDC or PMSM, with the possibility of being connected as a feedback sensor or a mains probe. The article describes the principle of functioning of the module together with the description of selected basic components.

Measurement of sound fields using non-contact optical methods
Karásek, David ; Skalský, Michal (referee) ; Havránek, Zdeněk (advisor)
The purpose of this paper is to assemble measurement chain dedicated to contactless measuring of acoustic fields emitted by test sources and to validate its results. At first author discusses possible optic methods which can be used to measure acoustic fields, then he talks about theoretical foundations which are needed to measure data and to reconstruct final data. The last two chapters are dedicated to cover basics about created program and to analyse various aspects which influence measured and reconstructed data. Created measurement chain is fully functional, at the end of this thesis are proposed some ways of improving
