[0046] Such as figure 2 As shown, the time response compensation method of the thermal distributed gas mass flowmeter comprises the following steps:
[0047] (S1) Calculate the measured value increment ΔU=U corresponding to time i according to the original measured value of the thermal distributed gas mass flowmeter i -U i-1 , where U i Indicates the original measured value at time i.
[0048] (S2) According to the two original measured values at the moment i and the fixed measurement time interval Δt at the previous moment, combined with the Kalman filter algorithm to recursively calculate the recursive steady-state response value corresponding to the original measured value at the i moment specifically,
[0049] (S2.1) Establish the state equation and observation equation of the thermal distributed gas mass flowmeter at time i based on the Kalman filter algorithm:
[0050] Equation of state
[0051] Observation Equation E 0 (k)=E(k)+v(k)...(6)
