Motion control during hanged object transportation
Richter, Jan ; Davidová, Olga (referee) ; Němec, Zdeněk (advisor)
The Diploma Thesis focuses on examination of most suitable optionsof movement regulation of pendent object from the perspective of various requirements on the course of the process as such. The environment of Matlab-Simulink was used for the analysis. The first part of the Thesis deals with the creation of the model of the whole system and creation of additional models of systems with similar, highly oscillating behaviour. The central part of the Thesis focuses on the design of suitable methods of movement regulation during translocation of the pendent object, which is tested on a simple model of travelling monkey. Four approaches to the problem solving were chosen: simple regulation by PID regulator, branched regulation, state regulation and predicative regulation. All solving options are being analysed and optimised and their results mutually compared according to requirements defined, such as: speed of the process, fluency of the movement, small pose overshoot or small angle of rope deflection.

Comparison of H-infinity and LQG controller
Friml, Dominik ; Blaha, Petr (referee) ; Pohl, Lukáš (advisor)
This thesis deals with the MIMO system analysis, with a comparison of a different frequency charactersitics, and including singular values characteristic. The H2 and H norms are defined for signals and a MIMO systems. A MIMO optimal control using an LQG, an H2 and an H control is defined and described. Their general advantages, disadvantages and similarities are summed up. An H2 and an H state controller and state observer synthesis is implemented in a MATLAB using linear matrix inequalities. Control of an inverted pendulum is designed using the H optimal cascade control, the H2 state control and the H state control. The results are compared with each other. The theoretical possibility of same H2 and H optimal state controller design is presented.

Design and control of self balancing robot
Jiruška, Jiří ; Pohl, Lukáš (referee) ; Blaha, Petr (advisor)
This thesis deals with complete design and manufacturing of autonomous two wheeled self-balancing robot. The goal of this thesis is to maintain the robot in up-right position and to follow black line using camera. The robot is controlled using Raspberry Pi and driven by DC motors. This thesis includes the design and implementation of hardware and software parts. Subsequently there was created the dynamic model in Matlab/Simulink. Based on this model, the LQR and PID controller was designed.

Control of Three-phase Sinusoidal Power Source
Žůrek, Tomáš ; Patočka, Miroslav (referee) ; Klíma, Bohumil (advisor)
This thesis deals with control of three phase inverter as three phase sinusoidal voltage source for UPS application. Thesis is split to two parts, teoretical and practical. Teoretical part deals with three phase inverter topology analysis according requirement of neutral line wire and possibilities of generating sinusoidal PWM in depend of topology. There are also analysed properties of contorled system and designed 3 regulation methods with simulations. Second part of thesis deals with realisation of sinusoidal power source with inverter borrowed by Elcom company. To inverter control is used digital signal controler TMS320F28335 with implemented control algorithms. There are also presented the measurement results of the prototype of power source. In conclusion, simulation results are compared with measurements and achieved results are summarized.
