Electrical Servo Drives for Critical Applications
Hubík, Vladimír ; Kurka, Otakar (referee) ; Ondrůšek, Čestmír (referee) ; Opluštil, Vladimír (referee) ; Singule, Vladislav (advisor)
The presented work deals with doctoral thesis named “Electrical drives for critical application”, which is solved in the Institute of Production Machines, Systems and Robotics. The paper tries to subsequently describe the progress during development of electric drive and to introduce the findings reached during project solving. The critical application requirements have been defined at the beginning, especially for the aerospace industry point of view. The work deals with the architecture of the control and power electronic, control software algorithms of the brush and brush-less BLDC motor with respect to the final certification aspects. It is also discussed the effectivness of the new development methods based on the modeling and simulation. The Model Based Design approach have been proved and verified during aircraft onboard equipment development. The findings of these are discussed at the end of this work.

MultiCopter Design
Picek, Matěj ; Pelikán, Petr (referee) ; Zdařil, Zdeněk (advisor)
In my work, I focused on the design of an electric multicopter for common and advanced users. The main objective was to bring a simple practical solution to the dron, which will correspond to the current functional and aesthetic standards of industrial design in the aircraft industry. Whole concept of the dron is designed to be as user-friendly as possible. Thanks to its simplicity, small dimensions and dron structure, it takes a minimal transport space and is almost instantly ready for use.

Analysis of results from experimental electrodischarge sinking of special materials for aerospace industry
Macháčová, Veronika ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The aim of this master's thesis is experimental electric discharge sinking of special materials for the aerospace industry. The first part is a general overview regarding the technology of electric discharge machining with emphasis on electric discharge sinking. Following this is a practical part devoted to the electric discharge sinking of the Nimonic 263 material with a copper tool electrode with a subsequent evaluation of surface and subsurface changes in this material. The wear of the tool electrode is also examined with the conclusion highlighting combination of machined material and tool electrode material behave in different working conditions and how the surface layer of machined material is affected.
