Advanced Submarine Technology - Project M. Control Experiments and Simulations. Phase 2.

Abstract

The aim of Project M is to demonstrate that the use of broad band active control, with a distributed array of electromagnetic actuators, can not only support a machinery raft but also provide a very high degree of isolation from the hull. In addition the raft can be adequately restrained, to maintain accurate alignment under heavy sea-way or manoeuvring motions, and longer wavelength structural resonances in the raft can be suppressed. This would allow larger lighter rafts can be used to accommodate machinery items without an increase in the acoustic radiation hazard. This document brings together a description of the work on the control theory, the simulations, the hardware upgrades and the results of the experimental program which validated the theoretical predictions.
