Dear All,
I have some time series data of various variables from my system that I would like to model. Say x(t), y(t), z(t),q(t)

The system is not that much black box that I know how z or q should change in terms of x and y.

My system is multi input multi output(MIMO). So I must somehow reach functions like z=f(x,y) and q=f(x,y) and use them for my modelling purposes. My ultimate purpose is to reach an input/output model of my system that I can use in the Simulink for my futher studies.

What are your recommendations? Some professional help would be wonderful.

Thanks for your concern.

 

We have developed a Windows program that might work. The program takes in time series data from a text file or spreadsheet and identifies Laplace or z-transform low order dynamic models (first or second order). There's a wealth of statistics that go along with the identification, but in general it's pretty simple to use. Also, you can identify single or multi input/output models using the program.
