Computer support realization of symbolic models in MATLAB
Valová, Alena ; Věchet, Stanislav (referee) ; Březina, Tomáš (advisor)
The aim of the bachelor's thesis is description of the functions tf (transfer function), ss (state space) and ss2ss (similarity transformation) that occurs in the programming language Matlab in the Control System Toolbox, and their subsequent implementation in the environment of programming language Matlab using the Symbolic Math Toolbox. This thesis is focused to implementation of algorithms that can solve these functions symbolically. By connection and reunification programs, functions can be converted from one form to another. The library is useful for teaching automation.

Vibration Harvester for Aircraft Applications
Rubeš, Ondřej ; Vetiška, Vojtěch (referee) ; Hadaš, Zdeněk (advisor)
This thesis is focused on modification of a design proposal of a vibration energy harvester for autonomous aircraft applications. Vibration energy harvester is mechanism, which converts vibration energy to electric energy. Its main parts are oscillating mass, magnets and coil for electromagnetics induction. The thesis is consisted of simulations of magnetics circuits, creating 3D model of harvester and simulations of oscillations with parameters from 3D model, magnetics simulations and with input sample of exciting vibrations.

Measuring and Visualizing Distance Sensor Data in Real-Time via Arduino and Xbee wireless communication to Matlab
Zapletal, Marek ; Liška, Radovan (referee) ; Karakhalil, Mourad (advisor)
Work describes making of measuring system consisting of ultrasonic sensor, programmable board Arduino, where the wireless communication is provided by Xbee modules. Theoretical part depicts the single components including the programmes for making the code necessary for proper function of the system. On the other hand, realization and creation of programmes is the centre of practical part of the work. System was physically made and the obtained data from distance sensor were in real-time transferred and depicted in MATLAB programme, where the data are filtered and the graphs of elapsed time- distance are drawn. This work is one of the first possible steps in making intelligent devices or robots from the general aspect of mapping, navigating and orienting in a surrounding area.

Recognizing of the gesture, based on data from accelerometer, used to control a car model
Zermegh, Tomáš ; Sova, Václav (referee) ; Lamberský, Vojtěch (advisor)
This project deals with the usage of development kit Chronos ez430 to demonstrate fundamental movements based on the recognition of gestures. Recognition of basic gestures for movements (forward, stop, backwards and turning) is the fundamental part of the work which is based on formulating algorithm. The formulating of algorithm for data processing runs under Matlab/Simulink. The algorithm is converted into the C language and with the help of Code Composer Studio is integrated into kit Chronos ez430.

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.

MATLAB/ Global Optimization Toolbox: Solving Optimization Problems
Švihálková, Kateřina ; Dvořák, Jiří (referee) ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The bachelor thesis deals with basic description of global optimization methods which are implemented in MATLAB environment. First part of this thesis describes two MATLAB's toolboxes -- Optimization Toolbox and Global Optimization Toolbox. This study also describes chosen algorithms from those toolboxes (Genetic Algorithms, Simulated Annealing, Pattern Search and Fminsearch) and describes it's implementation. The last part is focused on the solving of optimization problems. Rosenbrock's function, Rastrigin's function, Traveling Salesman Problem and Stepped Cantilever Beam Design Problem are being solved by methods mentioned above. Reached results of every task are compared to each other and evaluated.

Deformation, stress and safety analysis of the recumbend frame.
Verner, Jan ; Majer, Zdeněk (referee) ; Vrbka, Jan (advisor)
This work contains deformation, stress and safety analysis of recumbent bike frame from company AZUB. After introduction about history, definition of beam and beam assumptions, computational model of the frame was made fallowed the main solution. Three load states was checked - stillnes / uniform ride, deceleration and pedalling. The third one was subjected to deeper analysis. Bending problem in defined location was solved for all states. Inner stress resultans was solved as Von Misses stress, and the safet y was calculated. The fist state was compared with FEM. A program in MATLAB was made, enabeling calculation of user- selected frame geometry and loading.

Testing platform with 3 dof
Spáčil, Tomáš ; Houfek, Lubomír (referee) ; Grepl, Robert (advisor)
This thesis deals with development and construction of parallel manipulator with three degrees of freedom whose assumption of usage is testing tanks for NH3. In this work we are going to investigate the design of the mechanism in Matlab Simulink. Design of the electronic is introduced and also the control program is developed. The result of the work will be a prototype of manipulator.
