Original abstract
The task of synthesis of control circuit is to determine its structure and parameters for fulfilment of accuracy, stability and quality requirements of control process. A number of methods have been elaborated to design a control circuit. The differences in those methods are based partly on their complexity and partly on what indices of control quality they stem. There are indices of control quality in time, frequency and transform domain. The frequency characteristics are the basis of frequency methods. Most frequently the frequency characteristics are used in logarithmic coordinates. This paper will deal with design of digital controller parameters using the method of so-called standard logarithmic amplitude frequency characteristic of open-loop control.
Czech abstract
Úkolem syntézy je stanovení struktury a parametrů regulačního obvodu tak, aby byly splněny požadavky přesnosti stability a kvality regulačního pochodu. Pro návrh regulačního obvodu byla vypracována celá řada metod. Tyto metody se liší jednak složitostí a jednak tím, z jakých ukazatelů kvality regulace vycházejí. Existují ukazatele kvality regulace v časové, frekvenční a obrazové oblasti. Základem frekvenčních metod jsou frekvenční charakteristiky. Nejpoužívanější jsou frekvenční charakteristiky v logaritmických souřadnicích. Tento příspěvek chce ukázat návrh parametrů číslicových regulátorů použitím metody typizované logaritmické amplitudové frekvenční charakteristiky otevřeného regulačního obvodu.
