Hi,
is it possibile to use a model specified with FMU as a Grey-box?
The goal is to identify params in the FMU https://it.mathworks.com/help/ident/ug/estimating-nonlinear-grey-box-models.html.
We are currently developing FMUs with OpenModelica tool and we need to identify some FMUs parameters..

Yes, it is possible to use an FMU as a grey-box model in a parameter estimation task. An FMU can be thought of as similar to a sub-system in Simulink implemented using a Subsystem Reference or Model Reference block. In Simulink you can use FMUs exported from Simulink as well as other tools like Open Modelica. You can set the parameters of an FMU as tunable as outlined in this post: https://www.mathworks.com/matlabcentral/answers/468256-how-to-include-tunable-parameters-when-exporting-a-simulink-model-as-a-tool-coupling-fmu-in-r2018b-o
