Claim 9:
10. The system as claimed in claim 8, wherein the assembly of at least one distillation column is supplied with the air fluid, the target argon flow rate determined by the controller being determined additionally depending on a predictive value (Qpred) of the argon flow rate depending on the air flow rate (Qair) at the inlet of the assembly of at least one distillation column and on a yield (ρ) of said assembly, wherein the anticipation parameter relating to the variations in the dioxygen content measured by the sensor is a weighting coefficient of the predictive value of the argon flow rate, the target argon flow rate being determined as follows:

Qargon=Qpred×P+Δregul 

Where:
Qargon is the target argon flow rate,
Qpred is the predictive value of the argon flow rate,
Δregul is a required argon flow rate variation, and
P is the value of the weighting coefficient of the predictive value of the argon flow rate.
