Theatre Stage Control System with Graphics Interface
Ševcovic, Jiří ; Španěl, Michal (referee) ; Zemčík, Pavel (advisor)
This thesis focuses on a control system for theater scenes. The system is based on technology of industrial computers and can handle theatre scene equipment, such as slot. The asynchronous AC engines and computer controlled frequency changers are used along with various sensors. The control is done via CANopen protocol and the software was written using Control Web.

Usage of Modern Methods for Increasing Reliability of Control System Implementations
Szurman, Karel ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
At avionics control and critical systems is necessary guarantee a minimal level of fault tolerance and their high reliability. On the electronic components in these devices has an undesirable influence environment conditions and mainly cosmic ray. In this paper are described the most common failure types of semiconductor components and devices together with modern methods which can be increased the system fault tolerance and its overall reliability. There are introduced aspects of the avionic systems design due to finally certification and ways to evaluate its safety. This thesis describes design and implementation of the CAN bus control system for the FPGA platform which uses the CANAerospace application protocol. Created system design is improved by the TMR architecture. Fault tolerance of both system version is tested by the SEU framework which allows using the dynamic partial reconfiguration generate an SEU failures into running FPGA design.

Visualization and User Interface for Theatre Stage Control System
Kobza, Lukáš ; Ševcovic, Jiří (referee) ; Zemčík, Pavel (advisor)
This thesis deals with questions of modelling and 3D visualization. Also, it involves an overview of technical equipment on a theatre stage and control systems of this machinery with accent on user interface and all the interaction with staff. Afterwards, the main topic is the investigation of 3D visualization utilization technology in the field of theatre stage control systems and then the proposal and implementation of the theatre stage 3D visualization application follows in order to increase a clearness and safety of operation with the theatre control system.

Control of special purpose machine tool
Plocek, Jaroslav ; Holub, Michal (referee) ; Houška, Pavel (advisor)
The master thesis treats the design of control system of special purpose machine tool. The first part analyzes and compares two possible variants of control system which use either a CNC control system Sinumerik or motion control system Simotion. Only the variant with the Simotion control system is subsequently examined in detail: its hardware configuration, the selection of components and partly also the software solution. The thesis further deals with the safety of the realized control system and of the whole machine. There are described general safety requirements of machinery based on harmonized European standards and their specific application in the design of safety functions and the safety circuits of solved machine tool.

Design of a fault-tolerant control system for a self-balancing two-wheel vehicle
Matějásko, Michal ; Zouhar, František (referee) ; Grepl, Robert (advisor)
Tato práce se zabývá návrhem nového řídícího systému, odolného proti chybám, pro nestabilní samo-balancující dvoukolové vozidlo typu Segway. Původní systém vozidla je podroben analýze rizikovosti jeho součástí a na základě výsledků jsou navržena opatření pro zvýšení jeho bezpečnosti. Je navržena nová topologie řídícího systému obsahující dvě samostatné řídící jednotky, redundantní senzoriku a voter. Pro řídící jednotky byl vyvinut software obsahující bezpečnostní algoritmy a mechanismy přepínání kontrolních výstupů. V práci jsou také představeny dva matematické modely vozidla různé složitosti, které jsou následně využity při HIL testování nově navrženého systému. Celý návrh byl proveden s využitím nástrojů pro Rapid Control Prototyping.

Sinumerik tools for programming of rotational machine part
Slavík, Daniel ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This diploma thesis deals with a manufacture of rotating mechanical component on CNC lathe machine with Sinumerik control system. At first the chosen component is briefly described and then NC program is created in Sinutrain Operate 4.5 system. Afterwards the program is verified by simulation. Within the diploma thesis a technological documentation is elaborated that contains a new technological course of manufacture and a manufacture drawing of the component. The final part of this thesis is focused on technical-economic evaluation of newly designed manufacture with verification of cutting conditions and required output of the CNC machine. The outcome of the thesis defines an hour rate of CNC lathe and price of component that regards to newly presented manufacture.

Free Vibration Analysis of Machine Tool Parts by High Feed Rates
Zábojník, Petr ; Drossel, Welf-Guntram (referee) ; Blecha, Petr (advisor)
Rostoucích nároků na produktivitu obráběcích strojů je dosaženo zvyšováním dynamiky těchto strojů. S vysokou dynamikou se na stroji může budit volné kmitání jednotlivých součástí, které ovlivňuje přesnost pohybu posuvové osy stroje, stejně jako přesnost pohybu nástroje. V diplomové práci jsou zkoumány jednotlivé parametry stroje a řídícího systému a jejich vliv na nabuzené frekvence. Aby mohly být jednotlivé vlivy zkoumány, je v diplomové práci vytvořen zjednodušený model posuvové osy pro analýzu metodou konečných prvků v programu Ansys. Tento model je následně spojen s řídícím systémem v programu Matlab/Simulink, díky čemuž je umožněno teoretické zkoumání mechanických a regulačních vlivů na přesnost dráhy posuvové osy a kmitání jednotlivých částí stroje. Výsledkem diplomové práce je funkční propojení FE modelu a řídícího systému, který může být použit pro mnoho různých výzkumů, a na kterém byly zkoumány vlivy vybraných parametrů stroje a řídícího systému.

Fuselage and control system design of VUT 081 Kondor
Kalný, Jan ; Šplíchal, Jan (referee) ; Mališ, Michal (advisor)
This master’s thesis deals with VUT 081 Kondor composite fuselage design and control system layout design. Load computation and selection of critical load cases are made. Principal inner surfaces of the fuselage are designed with respect to basic ergonomic requirements of the crew. Construction materials are chosen and a layup of composite materials is performed. Fuselage FEM model is made in MSC Patran/Nastran system and the structure-strength analysis is given for chosen load cases.
