Analog system SW simulator
Košta, Ondřej ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
This Master’s Thesis focuses on development and realization of analog system software simulator for simulation of various kinds and orders systems and for function verification of microcontrollers’ control systems. The development and realization of PSD controller is part of this thesis as well. The simulator is written in C++/CLI programming language which combines fast execution of native code and provides an advantage of managed code which has its execution managed by the .NET Framework. The data acquisition is performed via National Instrument’s USB multifunctional DAQ. The PSD regulator is realized by using modern ARM processor architecture.

Measurement of the centrifugal acceleration
Košta, Ondřej ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
This work is concerned with design and realization of rotational speed sensor based on measuring of the centrifugal acceleration. The measuring chain is designed as wireless, because it is needed to transfer the information about acceleration from rotating shaft, so connection by wire is impossible. The measuring chain is realized by using convenient MEMS accelerometer, that's why the first chapter is dedicated to short introduction of MEMS technology. Then the reader is introduced to methods and physical principles of acceleration measurement. The two most used types of accelerometers, piezorezistive and capacitive, are described deeper. The last theoretical chapter deals with two ways how to determine rotational speed from acceleration. The process of design of the measuring chain is described in the practical part of work. There are reasons for choosing a microcontroller. Sampling and message sending algorithms are described, there is also a description how AP receives messages. The AP serves as bridge between transmitting part and PC. Measured data are processed by PC in developing environment LabVIEW. Then the virtual instrument, which process measured data and represents them on screen for the user, is described. Finally the mechanical parts of the centrifugal acceleration measurement tool are described.
