Cannot make Linearization work
Still after watching several tutorials I cannot make the Model Linearizer work as I hope it shoud (and how it seems to work for anybody else)
I have the following Simuling model:
Everything on Simuling works fine, I get this output from the measurement probe:
Then I mark the step input as Linear Analysis Point/Open-loop input (tried also with Input perturbation) and the probe signal as Linear Analysis Point/Output measurement. Then I start the Model linearizer (in many videos I see that it is called from a menu item that doesn’t show up in my Simuling: Analysis/Contro Design/Linear analsys, but I assume it is the same, probably just different software releases).
Finally, when I hit "Step" or "Bode", all I get is a flat response (basically only the steady-state value):
What am I missing? I also tried playing around with different operating points (i.e., [0, 1, 1.1, 2, ….] to no avail.
I would expect to get the same output, and from there extract the transfer function. Thanks for any helpStill after watching several tutorials I cannot make the Model Linearizer work as I hope it shoud (and how it seems to work for anybody else)
