The model is compared with a Finite Element model and is shown to give the same results.
The proposed model is thus effective.

**Control**:
Combines:
- the FxLMS-based adaptive inverse control => suppress transmission of periodic vibrations
- direct feedback of integrated forces => dampen vibration of inherent modes and thus reduce random vibrations
