Paramater Estimation App - Simulink

Hello all,

I wish to use to the Parameter Estimation Tool in Simulink and I am trying to follow this tutorial - https://nl.mathworks.com/videos/estimating-dc-motor-parameters-97057.html

But when I select - "New Experiment", I am not able to see any dialog boxes for Outputs and Inputs where I can put my time and output vectors as seen in the tutorial. Instead the following screen is seen.

In the video, the following options are avaliable,

I am using an active workspace. I can select Parameters to estimate, but not the outputs and inputs.

Can anyone please help? I am using MATLAB v 2020a.

Thank you very much in advance.

Hi Nimish,

If you closely observe the below two images:

First Image: Model

Second image: Parameter Estmation Window

You can see the in the Model, there is an input (voltage) and an output (speed). Since this was defined in model, in the second image it is reflected as PE/DC Motor1(Speed) as Output and PE/voltage1 (voltage). In your model it appears that you do not have any input or output ports so it is not detected in Parameter Estimation.

Hope it helps.
