Abstract (en)
[origin: WO2019207542A1] A control method for an internal combustion engine, carried out by means of a feedback control of the engine speed, based on an error (Err) of said engine speed, calculated between a reference value (Ref) and a measured value (Speed) of the speed, wherein said control comprises a sum (S2) of a proportional contribution (P) and an integral contribution (I), the method comprising a step of adding a derivative contribution (D) only when a first sign of said error and a second sign of a derivative of the engine speed are reciprocally concordant.
