Hello People ,
I am trying to model a system using the difference equations given below.In that if you notice in the first vi (Forum vi1) out of the three constants weight ang Kr0 are constant .
And the model fits with the measured data well when the BG constant is low initially (for the first increasing phase of the measured data) and the simulated breath fits well with the measured data in the final
constant phase when the BG constant is high.
So the BG constant increases with time .
Hence i tried to design the model such that the BG constant increases in a constant rate (i have used 55.55). (Forum vi2)But the vi gives same out for all the different changes that are made in the BG coeffient.
Please have a look .i am attaching a sample data with the two vis .
Thank you in advance
