Sensitivity Analyzer : How to use the requirement signal matching correctly

Greetings to all,

I am working on a problem where I need to optimize the output tension of a battery modeleld On MATLAB/Simulink, and to do so I am using the Sensitivity Analyzer app, to do so.

During the configuration I chose the requirement signal matching to match the mesured output signal to the experimental input signal.

The problem that I encountered is that my MATLAB/Simulink version -Unlike the documentation- does not have the input signal panel in the signal matching requirement:

Then I tried to run my model with the current configuration and I got this error message :

Is it an installation problem and is there a way to fix this ?

Thank you in advance.

Hi @zineb liamani

It seems like you are having trouble adding the experimental input signal in the "Sensitivity Analyzer App". The "Inputs" panel becomes active when there are "Inport" blocks in the model, allowing you to choose an "Input Signal" for "Signal Matching". Please refer to the example below for more details on the usage of "Signal Matching requirement".

Please find the documentation on “Signal Matching” and “Sensitivity Analyzer App” below for your reference.
