Implementation and analysis of control circuits in MATLAB/Simulink
Hanuš, Tomáš ; Houška, Pavel (referee) ; Singule, Vladislav (advisor)
The thesis is focused on comparing the characteristics of the most common types of controllers. This comparison is done in MATLAB / Simulink to model the DC motor. First, in the thesis, theoretical description of all structures controllers that are tested. This is specifically the PID controllers, PSD, PI-D, PS-D, S-PD, I-PD, PID filtering of derivative and PSD also with this filtration. Then there is the function given the DC motor and its mathematical description. In the last section of the theoretical part describes the different methods of setting regulators. In conclusion, this thesis compares the structure of individual regulators. There are the results. A comparison of their behavior with position control of DC motor.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Design, production and testing of education model "Helicopter with two rotors"
Zouhar, František ; Šolc, František (referee) ; Grepl, Robert (advisor)
This work deals with designing and testing of education model "Helicopter with two rotors". The first part is focused on the consturction. Function requirement and set of options of solutions appointed. One of options is chosen and developed by 3D CAD systems. Balance-sheet of possible materials is elaborated in the maximum level available motor pull. Central placing of model is proposed to be able to move in 3 axes. The force electronic are designed and constructed in the second part. Suitable sensors, control method of motor speed and power support are chosen. According to this part the printed circuit board is created, which work as interface between PC (card MF624) and helicopter. In the last part model parameters are identificated and PID control is constructed. Selection procedure of parameters is analyzed in detail, each difficulties are mentioned and obtained data are evaluated. PID control is realized by degrees with regard to complexity of controlling the axes. Problems with disturbance and its impact on control is discussed also.

Fare-Free Public Transport policy introduction in selected European states and municipalities in first two decades of 21st century
Čarek, Sebastián ; Kolman, Ondřej (advisor) ; Chmelová, Pavla (referee)
This thesis was written to create a missing complex study about Fare-Free Public Transport (FFPT) policy and to confirm hypothesis that abolition of fares are not generally accompanied by passengers increasing demand. Theoretical part describes public transport potential substitutes, for example competition in problematic individual car transport. In other chapters thesis summarises present known knowledges of public transport demand, financing by public service contracts and encapsulates experiences with Fare-Free Public Transport in Europe. Practical part includes four case studies: Tallinn, Frýdek-Místek, railway passenger transport in Slovakia and Prague Integrated Transport (PID). Analysis of PID and Tallinn confirmed that fare decrease in case of low fares already before act, does not entice additional passengers, because the demand is highly inelastic. But the important issue is that introducing of FFPT is connected with lots of side effects. Extraordinary space in thesis has policy of Free Trains in Slovakia, that caused many side effects that must have been solved in process to not damage paying passengers. Policy had important effect on public transport market in Slovakia, when ZSSK was pressed to depreciate own InterCity trains operated for own commercial risk and negative effect was also observed on private long-distance bus transport and on budgets of higher-level territorial administrative units.

Bus transportation in Prague and outskirts
Buzková, Jana ; Zelený, Lubomír (advisor) ; Mervart, Michal (referee)
The diploma thesis deals with the bus transportation in Prague and surrounding areas in the Central Region. It compares the Prague integrated transport system and Central integrated transport system. It deals with the question whether the use of two unrelated integrated transport systems is efficient on the same route and whether bus transportation is operated efficiently in selected region Praha - Neratovice. The survey of utilization is accompanied by information about carriers that perform bus transport in selected region, and information about their fleet. The aim of the thesis is assesing current situation, pointing out the differences between integrated transport systems and designing alternative solution.

Analysis of regional railway track
Baroch, Michal ; Zelený, Lubomír (advisor) ; Haas, Václav (referee)
Thesis contents information analysis about railway track number 173 Praha-Smíchov - Rudná u Prahy - Beroun with focus on stage Praha-Smíchov - Nučice. Aim of thesis was to determine the quality of the track and the possibility of eventual establishment of new railway stations.Hypothesis came true. It would be beneficial to the track if new railway stations were built. Nevertheless the realization is quite difficult than validated hypothesis.

Pražská integrovaná doprava
Rubková, Lenka ; Mervart, Michal (advisor) ; Melechovský, Jan (referee)
Bakalářská práce se zaměřuje na rozbor Pražské integrované dopravy, na nalezení jejich silných a slabých stránek. Teoretická část obsahuje IDS, praktická část se zabývá analýzou PID. Rozbor kapitol v praktické části odpovídá kapitolám z teoretické části. Nejdříve je zmiňováno o historii PID, o dopravních prostředcích v současnosti užívaných v Praze, kde je analyzovaná MHD a vnější hromadná doprava PID, dále jízdné, záchytná parkoviště P+R, vozový park a preference MHD.
