Un résultat intrigant en commande sans modèle
This addresses tuning challenges in model-free control for practitioners, though it appears incremental as it builds on existing controller comparisons.
The paper demonstrates through a mathematical example and computer simulations that an intelligent proportional-derivative controller (iPD) is easier to tune and vastly superior to both intelligent proportional controllers (iP) and classic PIDs in model-free control.
An elementary mathematical example proves, thanks to the Routh-Hurwitz criterion, a result that is intriguing with respect to today's practical understanding of model-free control, i.e., an "intelligent" proportional controller (iP) may turn to be more difficult to tune than an intelligent proportional-derivative one (iPD). The vast superiority of iPDs when compared to classic PIDs is shown via computer simulations. The introduction as well as the conclusion analyse model-free control in the light of recent advances.
