Hello Matlab and Simulink Users,
I am stranded on 13.1 Peregrine Falcon Dive Part 2 Task 4. I just cannot seem to get past it. Any help regarding it will be appreciated.Even the solution does not provide the desired output signal.
Thanks

Task 4 is where you add the substract block?
Can you please give more details are to what seem to be your issue?

Just went through this task. It works for me. First suggestion would be to restart MATLAB and see if the behavior continues. If you still are getting errors, are your low and high drag terms connected to the correct ports? Have you set the parameters of the switch?
Perhaps add an image of your model so we can see.

This is not even the only bug like this. I shouldn't have to restart the program multiple times to do ONE simple task.

There is a new issue affecting task 5 in R2021b. See this post for a possible workaround.

I have issues with task 4 as well... Can you spot the issue?

Sorry, I didn't get notified you'd replied. I think I figured out why you are getting this incorrect. I believe you copy/pasted the integrator that was already in the model rather than adding a brand new one. The one already in the model sets an initial condition that you do not want on your second integrator.
Please either set the initial condition to 0 in the new integrator block, or delete and add a new one from the library.
