Optimization, unknown parameters

Hi every one !!

i have small question concerning the identification of parameters in state space representation where i am beginer, i have the following equation

Cb*dTesm=b1(m)^b2-A(Tesm-T2)

my unkown parameters are b1 and b2.

what is the appropriate method that can be used to identify these parameters.

THANK YOU IN ADVENCE

I don't understand your equation

Cb*dTesm=b1(m)^b2-A(Tesm-T2)

What is m ?

Do you mean

Cb*dTesm/dt = b1*t^b2-A*(Tesm-T2)

?

yes exacltly ( just for t its m), i have the data for dTesm, m, Tesm, T2. These data are in form of vectors.

And what about A ? Is it also a fitting parameter ?

And you have data for dTesm ? How are they calculated ? As Tesm(m+1) - Tesm(m) ?

Well i had simulation on simulink and i extract the data from simulink with sampling of 1 , so the signal was continue, i turned them discret is this ok ?,for A is constant
