Drive Visualization of Four-Wheel Vehicle in Matlab-Simulink
Foriška, Aleš ; Klusáček, Ondřej (referee) ; Zavadinka, Peter (advisor)
This thesis deals with the formation of four-wheel drive vehicle visualization in MATLAB-Simulink. The begining of thesis is dedicated to the theoretical study of the history, production and usage of virtual reality. Next chapters describe the creation of virtual model of the vehicle and scene using SolidWorks, its adjustment in the V-Realm Builder 2.0. and implementing in the Matlab-Simulink environment. Using Matlab-Simulink (a tool of the Virtual Reality Toolbox) vehicle dynamics model was modified and linked with the virtual model, what enables drive visualization of vehicle. At the end of this thesis is applied joystick connection with a dynamic model, the user can interfere with driving during the simulation.

Algorithm for Reduction of Force Fight on Airplane Control Surface
Szásziová, Lenka ; Klusáček, Ondřej (referee) ; Tomáš, Jan (advisor)
Digitální Fly-by-Wire systém je novým přístupem k řídícímu systému letadla, na jehož základě firma Honeywell - HTS CZ začala výzkumný projekt s názvem “Next Generation Distributed Fly-by-Wire System” a tato práce je jeho součástí. Řídící plochy letadla jsou řízeny dvěma nebo třemi elektrohydraulickými (či elektrickými) servy a každé servo je ovládáno nezávislou řídící jednotkou. Díky provozním tolerancím systému a drobným odchylkám vstupních dat v řídících jednotkách, dostává každé servo mírně odlišné povely a rozdíl v poloze serv vede k namáhání řídící plochy i k namáhání serv. Hlavním cílem této práce je navrhnout algoritmus, který bude eliminovat rozdíly mezi polohami jednotlivých serv, a tudíž sníží sílu, která namáhá řídící plochu, na přípustnou mez. Implementace řídícího systému letadla byla do detailu analyzována a algoritmus redukce síly na kontrolní ploše letadla byl navržen a implementován v prostředí Simulink. Iterační kriteriální ladící metoda byla vyvinuta a za účelem co nejlepšího nastavení algoritmu redukce síly. Práce také analyzuje vliv časových zpoždení na sběrnici na kvalitu algoritmu redukce síly.

Modelling, identification and control of rotary pendulum
Klusáček, Ondřej ; Ondrůšek, Čestmír (referee) ; Grepl, Robert (advisor)
The diploma thesis deals with control of rotary inverted pendulum - Furuta pendulum. Solution for power electronics, sensors and coupling with PC is described, identification of parameters and nonlinear simulation model in Matlab/Simulink and SimMechanics toolbox is presented. Second type Lagrange equation is used for determination of equations of motion. Controll system based on state-space model of mechanism and LQR algorithm for design of state-space controller is used and switching between swing-up cotroller a stabilizing state-space control is achieved according to actual angular position of pendulum's angle. Input integrator eliminating steady state error was used with success.

Control of a servo-drive for a 3-axial rotary table
Trizna, Lukáš ; Klusáček, Ondřej (referee) ; Macho, Tomáš (advisor)
The aim of this master’s thesis Control of one servo-drive of three-axis rotary table is to develop a real-time motion control solution for the commercially available servo drives on the base of perspective solution available in the industry and the implementation of the chosen solution. The project includes the description of the current solution for the rotary table control, the description of suitable on the market available controllers, the rotary table control design for two selected controllers, the designed model on the base of identificated parameters of DC engine, the design of current, velocity and position regulators for the servo drive control, the servo drive control implementation by two selected controllers ESCON and EPOS2, the servo drive control function verification and the evaluation of achieved results.

Numerical study of classroom ventilation and its effect on the spread of harmful substances
Klusáček, Ondřej ; Prinz, František (referee) ; Elcner, Jakub (advisor)
The thesis deals with the numerical simulation of the effect of ventilation on the spread of pollutants in a classroom using the STAR-CCM+ program. The aim of the thesis was to create a realistic 3D model of the classroom, to select a suitable multiphase flow model, to evaluate the spread of pollutants under different forms of operation and to select the most efficient ventilation method. Using a Lagrangian multiphase flow model, the pollutant volume fraction was compared for each type of operation. The numerical solution was validated by means of an experiment carried out in identical rooms and under the same ventilation conditions. The resulting temperature and velocity fields in the classroom are also presented in the paper. Mechanical ventilation was found to be the most effective of the chosen methods. If the infected individual sits closer to the windows or doors, there is a lower risk of infection in the room
