Hi,
Have two versions of a "black box" function/model. No visibility on internals of function.
Single Input-Single Output with a set of tuning parameters.
Say for Version A I know tuning parameters. So can obtain step response.
Then for Version B would like some way to "auto tune" a set of parameters that will give same (or very similar) step response.
Can anyone give me an outline of a method how to achieve this?
I am not afraid of bit of scripting, if required.
Any information appreciated.

Firstly, can you share your black box model and what you have done so far?

Hi,
One option is to use Simulink Design Optimization .
Essentially, you would set up an optimization problem to tune parameters to minimize mismatch between simulated and desired step response. Please take a look at the doc and examples of this product and respond with any questions.
