I have a non-linear model I want to fit into an available to identify system parameters. I have used nlgreyest but the result is very different from the behaviour of the avaialable data.
My ODE model
. I want A,B and D to be the free parameters.

I have tried tightening the tolerance but the no improvement.
What I am looking for is how to set upper and lower bounds for these parameters since I have an idea of what they could be.
