Simulation Modeling of Electric Actuators for Selected Critical Application
Toman, Jiří ; Jalovecký, Rudolf (referee) ; Szabó, István (referee) ; Singule, Vladislav (advisor)
The dissertation thesis with the topic „Simulation Modelling of Electrical Drives for Selected Critical Applications“ focuses on the area of given applications in civil aviation. The selected application that the thesis deals with is an electrically driven and electronically controlled fuel pump supplying fuel to an aviation motor of the APU type. The thesis gives a comprehensive description of the design cycle of the unit and demonstrates implementing all the required critical functions. In the course of the design of the unit modern techniques in mathematical modelling, simulation, verification, monitoring and prediction of the operation status of airborne equipment were uses to the utmost extent. The purpose of these was to show the suitability of their application with regard to decreasing design time and cost, increasing lifetime and servicing intervals, as well as increasing user comfort and decreasing price. At the same time the required reliability was to be kept. The thesis also aims to prove and verify the suitability of using electronically commutated dc motors in critical applications in civil aviation. To reach this goal, it is necessary to design a robust drive control which would meet the given reliability requirements.

Programming of the two-axle drive with Maxon EC motors
Toman, Jiří ; Pazdera, Ivo (referee) ; Koláčný, Josef (advisor)
This work describes direction of the two-axle drive with EC motors type MAXON by means of control unit EPOS. Except own direction of EC motors it contains various types progress for proposal parameters of the continuous and discrete regulator with consequence verification and character comparison by means of programming surroundings MATLAB. After the successful simulation verification is introduced most suitable regulator for positional direction of the two-axle drive into the real control units EPOS which they are connected to EC motors MAXON with making sign EC- max 22. Further is realized communication setting among control unit type EPOS P and her subjection unit EPOS. Unit EPOS P is further connected with steering computer by means of serial bus RS 232. Other part these work is program for direction of the two-axle drive copying the inscription MAXON with use linear and circular interpolation. To creation of the program source code is used standard programming language ST. This program is realized in programming surroundings EPOS STUDIO which is added by the producer to control units EPOS.

FPGA application for control and modelling of BLDC motor
Sova, Václav ; Toman, Jiří (referee) ; Grepl, Robert (advisor)
Thesis deals with the challenges in the field of BLDC motors control with the utilization of Field Programmable Gate Arrays (FPGA). Using the modular dSPACE hardware with the FPGA board, these issues are solved: sensored and sensorless control, real-time simulation of BLDC motor and control of BLDC motor in degraded mode. FPGA design is made using the System Generator for DSP from Xilinx. The side effect of work is to show that with the expansion of high-level tools for FPGA design, the implementation of algorithms for FPGA is relatively quick and efficient and does not require years of experience and big knowledge of field programmable gate arrays. The implementation of algorithms on FPGA instead of processors brings many advantages, in the first place the high speed processing and low latency.

Evaluation of the Success of selected game skills in mens Volleyball extraleague
Toman, Jiří ; Vorálek, Rostislav (advisor) ; Petružela, Jan (referee)
Title: Evaluation of the Success of selected game skills in mens Volleyball extraleague Keywords: volleyball, serve, pass, success, player, team Objectives: The primary goal of this bachelor's thesis, was to comparison of two types of serves, namely jump float and jump spin serves and in addition, comparison of its passes. The secondary objective was the analysis of these two serves and reception of the ball which were assessted based on a scale of serve and a pass. Methods: To construct the analysis, data was collected and imputed to table using strokes. The data was obteined by closely monitoring games from match recordings. Furthermore, in order to analyse the data correctly, the game had to be split into individual sections of serves, passes and subsequent sets. The last method that was used in this work was the evaluatin scale, both for serves and passes. Results: The results were noted for clarity in graphs and tables, where they were commented.
