Thanks Greg for you answer.
Yes I'm sure i need to work in the frequency domain, I need to sweep all the frequencies from 5 to 2000 Hz.
I have already seen all the examples but all are in the time domain.
Basically I need to apply ADAMS/Control to ADAMS/Vibration instead that to ADAMS/Solver...
I have a simple 1 DOF mass spring damper system. The mass is forced by a swept sine force (5-2000 Hz). I used A/Vibration and I found the charateristic behaviour of this kind of system with an acceleration peack in the resonance frequency. Now I want to add a closed loop control aimed to...
