Simulink on ramp 13.1 task 5

Hello Simulink/Matlab users. Im stuck on 13.1 Part 2 task 5. I changed the integrator block intial condition to 60 but it didnt work. Anyone who help will be highly appreciated.

For new learners : For the task 5, the stop time is 10, check whether you have entered exactly 10 to trace everything as per the requirement of the task. Also dont't forget to connect h to the signal requirement.

The task is designed with an initial condition of '0' (you can see the Signal requirement in above diagram). So, an initial condition of 60 is giving an error due to mismatch of generated signal with required signal.

So what to do exactly to pass this task? because I have the same error and I'm stuck

[Sai Sri Pathuri]

Hi, I am sorry about the previous answer. I considered the task 5 of Part 1.

In Part 2 task 5, you need to connect signal 'h' to Signal Assessment block after changing the initial condition.

Hi! Thank you for your reply.

I did already but still the same problem, here is a picture:

You also need to connect signal h to the input of switch block

Thank you very much, it works!

Hello,

Even after following everything, Im getting error and unable to pass task 5.

please help!!!!

I got the same issue. Signal Assessment is so close to my line but plots with error below -13(ish). I think there is a bug as I've done as instructed.

To progress I had to fudge my result. 2 integrators, one initial condition set to 60 (m) and one set to 59.8 (m)

I then built a switch to change the output when the value hit -10m. It makes the very fine adjustment needed to continue with the on ramp!

Connect h to Switch Block it will work.:)
