The implementation of AC induction motor control algorithms in DSP 56F8xxx
Jenča, Pavol ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
In this bachelor’s thesis a control algorithms for induction motors are solved using the methods PDSFC and DTC. Functional algorithms are developed in C and assembly language and are transferred from Simulink to a digital signal processor series 56F8xxx of Freescale corporation. The thesis describes induction motors, used control methods, control schemes developed in Simulink, control algorithms in C and assembly language for each block of created schemes and comparation of simulated solutions.

Electrical integration of an auxiliary power units for truck
Pšenčík, Petr ; Veselý, Ivo (referee) ; Beneš, Petr (advisor)
This thesis aims to hardware and software integration of solid oxide fuel cell into a power generator for truck application. Requirements for individual components are defined, especially for main DC/DC converter which allows charging the battery pack with output from fuel cell. Then suitable components are found on the market and incorporated into hardware layout. Operation strategy with safety concept is proposed and consequently integrated into PLC in LASAL Class 2 environment. This is followed by definition of future work which includes testing and possible changes in components. Result is hardware and software design which allows construction of prove-of-concept prototype.

Implementation of Electric Motor Control Algoritms in CompactRIO systems
Gléba, Gergely ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
This master’s thesis deals with the implementation of existing algorithms of electric AC motor control in Matlab Simulink to LabVIEW Control Design and Simulation. The first part of the thesis treats with the deduction of a mathematical model of an asynchronous motor, permanent magnet synchronous motor and with the theory of vector control of AC motors. In the next part there is a brief guide to create simulation algorithms in LabVIEW environment and to create the model of a motor with EMI functions in language C. The last part contains the comparison of Matlab Simulink and LabVIEW simulation tools.

Electrical motors parameters identification using subspace based methods
Jenča, Pavol ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
The electrical motors parameters identification is solved in this master’s thesis using subspace based methods. Electrical motors are simulated in Matlab/Simulink interactive environment, specifically permanent magnet DC motor and permanent magnet synchronous motor. Identification is developed in Matlab interactive environment. Different types of subspace algorithms are used for the estimation of parameters. Results of subspace parameters estimation are compared with least squares parameters estimation. The thesis describes subspace method, types of subspace algorithms, used electrical motors, nonlinear approach of identification and comparation of parameters identification.

Permanent Magnet Synchronous Motor Parameters Identification
Dušek, Martin ; Veselý, Ivo (referee) ; Blaha, Petr (advisor)
This work deals with the on-line identification of permanent magnet synchronous motor parameters. There is discussed the use of four different identification algorithms based on the least squares method and MRAS. The functionality of the algorithms is verified in Matlab - Simulink environment. Simulation results are compared in terms of rate and accuracy of identification, resistance to noise and other factors.

Optimal control of a wind power plant
Paděra, Zdeněk ; Veselý, Ivo (referee) ; Zezulka, František (advisor)
The thesis first provides a brief introduction to wind energy and bring in the current status of this rapidly growing industry. Further, the distribution of wind turbines, their specific and general description of the construction is described. Emphasis is placed on wind turbine control system. The first goal was to build a simulation model of wind power plant in the MATLAB / Simulink usable for subsequent overall design of control system of wind power plant. Furthermore, the analysis of the control of individual components of power station in the light of the possibility of optimizing the operation and in particular the optimization of efficiency of plant, i.e. maximization of the reached performance is performed. In the last part of this thesis structure and parameters of individual control system of plant is designed and the results are discussed.

Synchronous motor parameter identification
Veselý, Ivo ; Veselý, Libor (referee) ; Blaha, Petr (advisor)
We often use a vector control for controlling of synchronous motor with permanent magnets. To get this control more effective we need to know the parameters of controlled motor. This document describes several methods, which deal with this problem and they are trying to expand them. We are talking about method uses Ohm’s law and the knowledge of motor model and method uses improved frequency analysis. The text below includes the principles of these methods and also identification verification of parameters by means of simulations on a created motor model. The final result of this work is the library of functions, which identificate on the basis on the improved frequency analysis.
