The aggressiveness of a PI controller is defined and a quantitative characterization is given in relation to the ratio of the proportional and integral actions of the controller. This concept provides simple analytic design relations for tuning PI controllers. It is illustrated by simulation results obtained with a test batch of processes representative of industrial applications and by control of a real water tank. Such results show the link between the aggressiveness of the controller and the minimum of the Integral-Time-Absolute-Error (ITEA) performance index.
V článku je navržen nový koncept agresivity regulátoru jako podíl proporcionálních a integračních zásahů regulátoru. Tento koncept vede k návrhu nových pravidel na nastavení PI regulátoru. Vše je simulováno na příkladech včetně laboratorního modelu vodních nadrží. Výsledky ukazují na úzkou vazbu mezi kvalitou regulace (ITAE) a navrženou agresivitou.
