use A / Control in the frequency domain combined with A / vibration
use A / Control in the frequency domain combined with A / vibration
(OP)
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 modulate the input force in order to maintain the mass acceleration to a required value (e.g. 1g). So I need to use A/Control in the frequency domain using as input of the Adams plant a vibration input channel and as output a vibration output channel. Someone can help me, is there any tutorial or guide useful to solve this problem?
Thanks, Vincenzo.
Thanks, Vincenzo.





RE: use A / Control in the frequency domain combined with A / vibration
Anyway 4 examples are given in the controls folder, I'd have thought running them would be helpful. I use neither product so that's all i know.

RE: use A / Control in the frequency domain combined with A / vibration
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 hope that someone can help me.

Vincenzo
