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.
