<p>Method of estimating a flow of gas (18) in an enclosure (14) maintained in a regime of reduced pressure in relation to the gas, comprising: - a measurement, as a function of time, of a flow of the gas Jmeasurement in the enclosure, and - an estimation of values of parameters A and B which is implemented in an iterative manner while reducing an estimation error based on a difference between Jestim(t) and Jmeasurement, and in which, when Jmeasurement corresponds to a rise in pressure of the gas in the enclosure, Jestim(t) is calculated according to the equation: (I) and when Jmeasurement corresponds to a fall in the pressure of the gas in the enclosure, Jestim(t) is calculated according to the equation: (II)</p> |
