Simulink Parameter Estimation (CMD) - OutputData only partly available

Good Afternoon,

I want to estimate parameters for a Simulink-Model. It has two phases, charge and discharge. I only have the experimantal data for the discharge-phase to base my parameter-estimation on. Nevertheless, my Simulink-Output is continuous, consisting of both charge and discharge-phase.

What can I do? I think simulink is not able to shrink the output-signal to the relevant part?

Best Regards, Florian

Why don't you only run your model from the start-end of the discharge phase?

Another option is to write a custom cost function that only uses simulation results from discharge phase. That would require setting up the estimation problem through code instead of a GUI.

The easier option would be to simulate the charge state, save results using SimState and run discharge phase for parameter estimation by initializing from SimState.
