Temperature control
Soviš, Jiří ; Glos, Jan (referee) ; Richter, Miloslav (advisor)
The thesis deals with the issue of temperature control by means of an uncontrolled source of waste heat in a closed room. The main purpose of this thesis is to get acquainted with problematics and technology used in the field of HVAC. Part of the thesis is a solution design of temperature control in which the heat loss from the compressor is used to heat the compressor room and as a supplementary heat source to the production hall to reduce costs. As part of the algorithm solution, was created a temperature model, developed in Matlab / Simulink, which was used to design a PI controller using integral quality control criterion ITAE and Nelder-Mead simplex.

Microprocessor-controlled autonomous source of constant current and voltage
Kováč, Marek ; Lattenberg, Ivo (referee) ; Pavelka, Ondřej (advisor)
The task of bachelor thesis is proposal of switching source for the construction of leadacid battery charger 6/12V controlled by microprocessor. It is based on buck converter of voltage. The first part presents the activity of converter and properties of lead-acid batteries, followed by a proposal of converter for a given application. The second part describes a criteria for selection of individual components and dimensioning them. The result of this thesis is simulation of converter in PC program Micro-Cap 9, along with the necessary calculations, a proposal of circuit with the calculation of inductor and methods of measurement of output quantities. Finally, is realized circuit board with a couple measurements and control program for the microcontroller. The entire proposal is focused to achieving the greatest simplicity of facility and efficiency and quality of charging accumulators together at low cost to the product.
