Flow Measurement of Hot Dusty Gas
Dostál, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with the measurement of hot dusty gas. The introduction outlines the problems of measurement. Another part of the work contains a theoretical introduction to the measurement of gas flow. In successive chapters the basic principles and characteristics of suitable methods for measuring the hot dusty gases are described. Finally, the function blocks are implemented in the Simatic STEP7 for calculation of volume flow rate and blocks are tested on PLC.

Equivalent circuit realizations of the simple chaotic oscillators
Kobza, Jaromír ; Dostál, Tomáš (referee) ; Petržela, Jiří (advisor)
The aim of this paper is to introduce with basic theory the problems encountered when considering the circuit implementation of autonomous RC chaotic oscillator with nonlinearity. All oscillator prototypes are based on one type of universal oscillator circuit. This circuit is able to generate a lot of attractors on condition of different entrance parameters. The design is based on a mathematical simulation, which includes the generation of electronic circuit values. The work is focused the transformation of these values to operational circuit configuration and simulation in a circuit simulator. The final task is to acquire chaotic attractors. Oscilloscope and spectrum analyser photos will verify the operation.

Function block for Simatic, Sinamics devices applied in position applications
Hložek, Vojtěch ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
The objective of this Bachelor's thesis was to make a series of function blocks and functions which would establish a communication between the programmable logic controller (PLC) Siemens S7-300 and the drive system Siemens Sinamics S120 through Profinet or Profibus and datagrams. The function blocks adjust the datagram parameters through which we can control motors connected to a drive system. The functions were made for easy and fast control of the basic motor operations (startup, shutdown, etc.) . The thesis includes a definition of a used software, hardware and the algorithms of the function blocks and functions.
