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

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.

Here's my signal... can you guess what is wrong with what I am doing?

Cris LaPierre 2023-9-20

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.
