I am trying to simulate an example explained on the website https://home.wlu.edu/~levys/kalman_tutorial/ Part 14. On this example, the author is fusion two noisy temperature measurements in order to get a filtered one using Kalman filters.

The example is simple and very well done by the author but I am facing some difficulties to implement that on Simulink.

Here is a picture of my model (I also attached the slx file):

And this is the error:

I appreciate any help !! Thanks !!

Kalman filter block doesn't have the capability to do sensor fusion. Instead of Kalman filter block use Extended kalman filter (EKF). Multi-sensor example : this example showcases how extended kalman filter is used for sensor fusion.

Thanks for you help !

I tried what you said and it seems to be correct now. I am still new to Kalman Filters to say it is 100% correct but I got similar results comparing to the website I was referencing to.

I attached the model in case someone wants to check it out !!!!
