Hello, I can´t answer the last task, task 9, of the section 8.1 of the simscape onramp course, I do exactly what I´m requested to do but I always get it wrong, I´ve been for several hours trying it but I simply don´t understand what I´m getting wrong. I´ve looked for the answer on Youtube but literally nobady has upload it, at least I haven´t found anybody, does anybody knows how to obtain the answer or can anybody tell me where can I find the way to solve it?, thank you!

Hello Juan,
can you provide insight into what is says is going wrong? There are 2 validation check marks that need to be passed for this one. Did you modify your PID controller to only be a PI controller (look for a drop down box). It can be solved.

anyone on this thread, if you are still having issues, can you take a screen shot of what your scope output is? This will show if the model is running as expected. It should look something like this:
John, your issue is that there the connection between the inertia should not also be connected to the rotational reference. This is essentially locking the rotor in place.

See Joel Van Sickel provided diagram dated 6 April 2021.
On my case, the problem are the connection between the Controlled Voltage Source, the resistor, inductor, Rotational Electromechanical Converter and reference.
Just followed Joel's diagram for it.

I am unable to solve the last task even after trying everything mentioned above. This is my circuit.

I have the same issue. The inertia block has this question mark on it. I have no idea what I did wrong. Everything else seems to be right except this part.
