Description
| - V průmyslové praxi jsou preferovány postupy optimalizace regulace, které nevyžadují teorii. Proto experimentální metody jako je např. metoda Zieglera a Nicholse si udržují svou popularitu, ačkoliv v současnosti k vyvolání netlumených kmitů je preferována metoda relé vloženého vloženého do zpětné vazby, prototože nevyžaduje kritické seřízení regulátoru. Navržená metoda využívající globální optimalizační přístup je založena na indikátorech optimální regulace vyplývajících z průběhu Nyquistovy křivky může být aplikována v praxi, (cs)
- In industrial practice, controller parameter optimization procedures that do not require any theory are strongly preferred. Therefore, the experimentally based methods such as the classical Ziegler and Nichols method retain its popularity. Nowadays, the Relay Feedback method is preferred because the temporary use of a relay in the control loop enables to avoid the critical controller setting. Proposed global optimization approach based on the indicators of optimal control defined by means of Nyquist plot is that having the chance to be applied in practise, because it can be simply carried out on-line by additionally exciting the control loop by a sinusoidal signal not greatly disrupting the controlled process. The evaluation methods are presented in the paper with the motivation to overcome disadvantages of the Relay Feedback method especially loss of control function during the identification phase. Goal is to design an adaptive PID controller ready for operating in real conditions.
