Parameter estimation with the PDP manager

Postby Rodrigo » 24 October 2018, 20:31

To insert data not available in the library of the COCO using the (PCD manager) it is necessary to provide several data, this data is very difficult to find. Does COCO make an estimate of this data? Thank you!

The PCD manager itself can fit the parameters of temperature dependent correlations. Alternatively you can fit these offline with any other program (Excel, Matlab, Scilab, ...) and just enter the parameter values.

How can I estimate these values in Excel or Scilab?

In Excel you can set up the equations for the total deviation and use the Excel solver to minimize the error. In Matlab you can use the optimization toolbox, or use e.g. the fminbnd function.
