Unable to assign Input Data in the Parameter Estimation tool
显示 更早的评论
Hello everyone. I am trying to learn the parameter estimation tool in Simulink. However, I cannot figure out how to import the Input data. Output data is the only section that appears on screen. Every tutorial I encountered, like here: Estimate Parameters from Measured Data - MATLAB & Simulink - MathWorks Benelux , there is a distinct Input tab. Am I doing something wrong? I cannot find anyone else who had the same issue. Thx!

Hi Ruben,
It seems that there is no root-level 'Inport' block in the SLX file. The 'Inputs' panel in the "Parameter Estimator" App is not displayed when there is no root-level 'Inport' block.
You can refer to the following documentation to learn more about 'Model Requirements for Importing Data':

Hi Nick, thank you for the answer.
I cannot get it working.
I do not know what you mean with "root-level" blocks, but I have a Inport block in my model as shown below.
This is a submodel, part of the control loop:
Also, I made sure Signal Logging is checked in the settings menu. I tried to made the signal arrows coming from the Inport block log the data via the property menu, but that doesn't make the Inport tab show up in the Parameter Estimator tool.
I appreciate your help already. Thanks in advance.

Hi Ruben,
The first file in the heirarchy is at the root-level. For example, in this case 'untitled' is at root-level.
Could you please share the SLX file of the model? This will reproduce the issue and investigate further.
