This paper suggests to replace PIs and PIDs, which play a key rôle in control engineering, by intelligent Proportional-Derivative feedback loops, or iPDs, which are derived from model-free control. This standpoint is enhanced by a laboratory experiment.

Keywords: Model-free control; intelligent proportional-derivative feedback (iPD); PI; PID; Riachy's trick
