where:
P(t) is the value of the anticipation parameter relating to the variations in the dioxygen content measured by the sensor at time t,
P1, P2, P3 are possible values of the anticipation parameter according to the variations in the dioxygen content measured by the sensor,
PV(t) is the value of the dioxygen content measured by the sensor at time t,
τ is a predetermined period of time, and
S is a predetermined threshold.
