Pressure and Flow Rate Regulation Design for Pump-Tank System
Kovář, Jiří ; Němec, Zdeněk (referee) ; Svoboda,, Miroslav (referee) ; Březina, Tomáš (advisor)
The proposed work is dealing with control design of pump-tank system as part of broader water-supply network with using of mechatronic approach. The main goal of this work is design of control for regulation of flow, pressure and water level in tank in water-supply network of Vsetin city. This water-supply network consists of various components, such as pumps, pipes, valves, tanks etc. For the purpose of the control design is necessary to create a model of pipe network. The solution of hydraulic analysis is obtained by using the gradient method, which was implemented into the software solution named ADAM. The results of hydraulic analysis are compared with measured values of flow and pressure and difference of these values has to be minimalized by proposed calibration and verification process. The calibration and verification process was implemented in software ADAM. The essence of design control is formulating control problem as optimization problem. Therefore the output of higher control layer is set of procedural rules, which determines for example speed of pumps in time etc. Results were verified by using for this purpose developed computational server (ADAM Server).

Leak testing of pneumatic components
Staňo, Martin ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This diploma thesis is focused on the issue of pneumatic components testing and air leakage measurement. The current state of the given issue is summarized based on the analysis of leak testing methods in accordance with valid legislation. The aim of this thesis is to design methods for pneumatic components testing according to specification. As part of method verification, a pneumatic circuit with a pressure control system has been assembled, on which functionality tests of provided components and leak tests by the pressure-drop method have been performed. The results of these tests have been subsequently evaluated as consistent with the specification.

System for measurement and control of pressure in vacuum apparatus
Sedlář, Jan ; Steinbauer, Miloslav (referee) ; Juřík, Karel (advisor)
The aim of the bachelor's thesis is to create a system for measurement and control of gas pressure with available vacuum components in vacuum apparatus. After conducting research in the introductory sections of the thesis to better understand the issue and determine suitable problem-solving approaches, the goal of the thesis was implemented based on the theoretical design. The chapters of the thesis discuss the selection of appropriate components and their integration into the functional unit. Both hardware and software solutions implemented in the thesis are described. The automated pressure control in the apparatus is built upon multiple supporting resources of hardware and software nature, which combined create an automatically designed controller that enables easy achievement of the desired operating point for further research in the vacuum apparatus.
