Hello forum, I have a dynamic model of a linear system (A, B, C and D matrices) and so it is known the FRF (H) of it. In particular, H is known for the whole range of frequency and it is as follows:
Now, I would define a certain input signal (let say D1) so that the response of my system is equal to a signal with a constant amplitude of 5 (for example) and phase 0. For this reason, my drive is designed as follows:
But the time response of my system, calculated with lsim it is something completely different.
Can you explain why?

‘Can you explain why?’
Perhaps, but definitely not without seeing your code.
