Although I correctly configured the model blocks and parameters accordingly to the directions, the training evaluation said my output did not match the answer. It prevents me from proceeding to the next task.
Here I attach two snapshots of the evaluation plot of Section 7.1 Task 5 where the problem occured.
The first picture shows comparison of the signals spanning to the end time (10sec). It looks to me exact agreement between the requirement and my signal, but it indicates slight discrepancies in the beginning of simulation (from 0 sec to around 1.0 sec) shown by the red dots. Due to these errors, the evaluator says my signal is incorrect.
The second picture zooms into the details of the red dots. It looks to me my signal has a slight delay to the answer.
I confirmed that my setup is consistent with the directions and the results unchanged even after several retries from the beginning of Section 7.1.
I am wondering if there is another parameter to be adjusted, which is not explicitly directed.
Can I have your help for solving this problem?
