Abstract
Diplomová práce se zabývá regulací prihrívání vysokotlaké páry pomocí kaskádní fuzzy regulace. Popisuje návrh fuzzy regulátoru vcetne jeho vnitrní struktury a vybírá nejefektivnejší struktury vzhledem k parametrum regulovaných soustav. Simulace jsou provedeny na lineárním modelu systému a lineárním modelu systému s promennými parametry. Pro jednotlivé simulace je vybrána nejvhodnejší sada parametru pro fuzzy regulátory. Modely a návrh struktury fuzzy regulátoru jsou vytvoreny v simulacním prostredí MATLAB/Simulink.
The diploma thesis deals with the controlling of the high-pressure steam superheater, using cascade fuzzy control. There is described the fuzzy controller design, including its internal structure, as well as the choice of the most effective structure according to the parameters of the controlled systems. The simulations are performed on a linear model of the system and on a linear model with changeable parameters. For each simulation, the best fitting set of fuzzy controller parameters is chosen. The models and the simulation design of the fuzzy controller have been created in MATLAB/Simulink software.
