New Hybrid Methods for Robust and Automated Parameter Estimation of Mechatronic Systems
Najman, Jan ; Štefek, Alexandr (referee) ; Opluštil, Vladimír (referee) ; Grepl, Robert (advisor)
The thesis deals with the development of a new hybrid optimization algorithm for mechatronic models. The introductory chapters are devoted to a general description of the problem of estimating unknown system parameters, based on the developed mathematical model and measured data. Furthermore, an overview and a brief description of available optimization algorithms that are suitable for solving this type of problem is given. Based on the research study, the specific objectives of the paper are then formulated. In the second part of the thesis, a newly developed set of mechatronic models created using physical modelling tools is described. Subsequently, a comparative test of the speed and success rate of the selected optimization algorithms is performed using these models. Based on the results of this test, the design of a new hybrid algorithm is proposed, which is then tested and compared with the other algorithms. Finally, several new auxiliary functions and tools are presented to detect and analyze improperly designed parameter estimation problems.

Modelling, Optimization and Control Design for Strongly Nonlinear Systems with Discrete Sensors
Bastl, Michal ; Štefek, Alexandr (referee) ; Opluštil, Vladimír (referee) ; Grepl, Robert (advisor)
The main motivation for this effort was international cooperation on modeling and control design for the stabilization system of the naval satcom antenna. The dissertation focuses on the design of models based on ODE and DAE from the perspective of mechatronic design. It mainly discusses the possibilities for simulation with a fixed step solvers, what is a necessary condition for real-time simulation and other use of modern approaches such as RCP and HIL. Furthermore, the work deals with modeling of friction, which is due to the strongly non-linear properties problematic for numerical models. The last output is the simulation comparison and verification of the possibility of implementing the incremental encoder into the Kalman filter algorithm.

Modeling and control of rear driven axle for Formula Student
Kavec, Matúš ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on design of controll structure of Formula Student monopost. Part of the thesis is a design and subsequent debgging ofthe model so it has the best possible response compared to reality. A PID controller with two degrees of freedom was used to create the control structure. Created controll structure has the task of regulating the system to the required value. By reducing skid, which is often unwanted in race cars, we can achieve better response while accelerating.

Design of control circuit for towing dynamometer
Rýznar, Jan ; Němec, Zdeněk (referee) ; Cejpek, Zdeněk (advisor)
This bachelor’s thesis is focused on design of a control circuit for a towing dynamometer. In the introductory part of the thesis is a detailed description of the towing dynamometer, including its main parts, which are necessary for proper operation. The next chapter is devoted to creating a dynamic model of an existing prototype using Simscape. Furthermore, based on the conditions from the dynamic model, a control circuit is designed, which is introduced in the form of a program into the control unit of the towing dynamometer. Based on the measured data from the transient responses, the function of the controller is gradually tuned to a satisfactory result. Finally, the function of the control circuit is evaluated and then measures to improve the stability, quality and accuracy of control are proposed.

Condition monitoring of mechatronic systems
Horňan, Bohdan ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This thesis is concerned with condition monitoring and quantitative analysis of synchronous motors. Constantly rising requirements on the reliability of motors develop new methods of predictive diagnostics, which can identify failure conditions in the initial stage. Created mechatronic systems with the implemented failure from pre-prepared PMSM model are tested by unconventional condition monitoring methods. Software solutions of diagnostics and model designs of the mechatronic systems are implemented in MATLAB & Simulink. Part of this work is also a short introduction to the issue with necessary theoretical fundamentals and research of some selected methods of predictive diagnostics.

Development of database of mechatronic models in Simscape
Al-Dailami, Zaid Abdulqudos Abbas ; Najman, Jan (referee) ; Bastl, Michal (advisor)
Tato práce se zabývá především vývojem databáze modelů mechatronik v nástroji Simscape. Je rozdělena do tří hlavních částí a to následně: První část popisuje nástroj Simscape a jeho možnosti . Práce poskytuje návrh, jak nastroj použít při vývoji modelů a jak se liší od jiných způsobů modelování. Druhá část obsahuje některé mechatronické modely založené na Simscape. Některé z modelů jsou také vytvořené pomocí standardního modelování Simulinku, a ty lze porovnat s dříve uvedenými modely. Třetí část je zaměřena na jeden z dříve navržených modelů se stejnosměrným motorem. Tento model se používá k vyhodnocení, odhadu a optimalizaci skutečných parametrů stejnosměrného motoru, obsahuje také popis, jak vygenerovat c kód z modelů Simscape, abychom jej použili v HIL.

Thermal Model Of A Room In Matlab Simulink And Simscape
Glos, Jan
This paper deals with creating a thermal model of a room using Matlab Simulink and Simscape library. The model is created based on building documentation and it is evaluated against the measured temperature with good compliance. The model can be beneficially used for control algorithm verification, which is quite time consuming in real-time due to large time constants. Using the proposed model the development time can be substantially reduced.
