Hello Harald Kirchsteiger

thank you for your answer

I already know that method, but I need to program it using Simulink block "Matlab function".

So if you know how to do it or if anyone knows how to do it please tell me.

Hi Youness Hamidou

Since you already know the method that is similar to the one posted by Dr. Harald Kirchsteiger, then you can easily construct the Observer in Simulink using the basic blocks.

If you want to learn how to use the MATLAB Function block, posting your question appropriately at the MATLAB Answers community may get a better response rate, technically.

Hello Youness,

I hope this example can be useful.

I set a very simple example that you can fill and modify according to the model of your interest.

Hello Dr. Pierpaolo Dini

Thank you for your answer, Its the method that I was looking for.
