Hi Sudchai ,
Just for the hint
Double-click on the Discrete PID Controller block to open the Block Parameters dialog and set the requested parameters
Hope it helps
Hi Anmol
It was a bug. Yesterday, I do nothing but I pass the task.
Hi Sudchai,
What exactly is the bug? Can you explain in detail.
I am not sure but it is about the Inertia: w
Did you change the sum to |+-? It is not explicitly mentioned in that task. This worked for me, I had the same problem.
Can anyone help send me a solution?
For me the solver block was not connected to the system, once I did that I was able to complete the task.
any solution for it?

Hi, I faced a similar error when trying to do the Simscape Onramp. The error occurs in this particular step even if the earlier steps are correct due to an absent scope block as mentioned in the instructions.
A more nuanced error can occur in the presence of a shortage while connecting the Rotational Electromechanical Convertor in Task 3. It does not produce an error earlier but results in a mismatch in the block value in Task 9 of the onramp. Attaching both the images for reference.
