Summary

[edit]
Description
English: Influence of the parameters on the convergence:
  • P
    • high P: fast (the nominal value is reached early) but not precise (important oscilations around the nominal value),
    • low P: slow (the nominal value is reached late) but precise (few oscilations);
  • I
    • high I: slow, but precise (at the beginning, the farthest value is quite close to the nominal value),
    • low I: fast, but not precise (at the beginning, the farthest value is quite away from the nominal value);
  • D
    • high D: slow (it takes a long time until the values stay in the acceptable range) but precise (the range becomes narrow),
    • low D: fast (the value get fast in the acceptable range) but not precise (the range stays quite wide).
Français : Influence des paramètres sur la convergence :
  • P
    • P élevé : rapide (la valeur nominale est atteinte tôt) mais imprécis (oscilations importantes autour de la valeur nominale),
    • P faible : lent (le système met du temps à atteindre la valeur nominale) mais péecis (peu d'oscilations) ;
  • I
    • I élevé : lent, mais précis (au début, la valeur la plus éloignée est relativement proche de la valeur nominale),
    • I faible : rapide, mais imprécis (au début, la valeur la plus éloignée est relativement éloignée de la valeur nominale) ;
  • D
    • D élevé : lent (il faut un temps relativement long pour que les valeurs restent dans l'intervalle acceptable) mais précis (l'intervalle devient étroit),
    • D faible : rapide (les valeurs restent dans un l'intervalle acceptable au bout d'un temps relativement faible) mais imprécis (l'intervalle reste large).
