Control system of active magnetic bearing
Kolařík, František ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
Thesis deals with active magnetic bearing (AMB) levitation control design. Its prototype was done in FSI collaboration with FEKT VUT Brno. The research is focused on communication tools and mathematical model making as well as general AMB issues. Based on this the control design is done an experimentally verified.

Control units for small EC motors with universal software interface
Vetiška, Jan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This graduation thesis deals with the design and realisation of the universal control unit for the electrically commutated motor ( EC motor). Was to accomplish the market research of control units for EC motors and compare of parameters of control units with requirements for the universal control unit of EC motors. From the research ensued that on the market it is no unit with the open system which could enable substitute particular control loops by own loops. Based on this evidence it was approached to own construction of the universal unit. For the design it was used the access hardware in the loop a software in the loop. It was performed the design of particular sections of the unit, manufactured the power section and this power part was tested by the help of the developmental and simulation software Labview. Furthermore it was proceeded for the realisation of the integral control unit and for supplementation of the existing software of the control unit about appropriate drivers and it was undertaken the modification of the control algorithm for the need of EC motor. On the end of this project we tested achieved parameters of the control unit.

Modification of 3D milling machine to 3D printer
Halamíček, Lukáš ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This thesis deals with rebuilding of engraving machine to 3D printer. In the first part it describes possible 3D printing technologies and its utilizations in rebuilding. In the next section suitable parts for reconstruction are chosen and described. Then the controlling of heating bed, hot end and filament feed is realized by using software TwinCAT by company Beckhoff. Functional 3D printer should be result of this thesis.

Modelling of mechatronic system with flexible parts
Kšica, Filip ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with the simulation modelling of mechatronic system with flexible parts using ADAMS and Matlab/Simulink. The beginning of thesis is dedicated to the summary of available methods of modelling mechatronic systems with flexible parts. Next chapters describe different approaches of modelling flexible parts using analytical and numerical methods. In the following step, model of particular mechatronic system is created. System itself consists of a flexible beam part, electromagnetic vibration exciter and vibration power generator. Each part of the system is created separately in variety of programmes, including FEMM, ADAMS and Matlab/Simulink. At the end of this thesis, co-simulation of ADAMS and Matlab/Simulink is used to describe behavior of the complete system, especially energy conversion efficiency of vibration power generator and its impact on the system.

Spindles actuator of turning machines
Hadraba, Petr ; Vetiška, Jan (referee) ; Hadaš, Zdeněk (advisor)
This thesis deals with dynamic modelling of actuators of multispindle automatic lathes TMZ842NG and TMZ867NG in MSC Adams software. The main objective was to assess dif-ferences between the individual spindles actuator systems and the influence of shortening material on the system. This thesis deals with the possibilities of dynamic modelling in MSC Adams, mainly with the application of the Machinery module. The choice of the final model for main analysis is based on the model's assessment.
