Book excerpt: This study was motivated by the need to control noise in naval vessels in order to reduce their detectability and hence vulnerability to enemy attack. This report provides a detailed review of controller technologies & algorithms that could be used for active noise, vibration, & structural acoustic control in ship structures. The review focusses on a wide range of controller technologies, methodologies and algorithms such as feed-forward control; feedback control; adaptive control; control of tonal noise; control of broadband noise; decentralized control; neural network control; active engine mounts; active noise cancellation; active vibration control; and active structural acoustic control. The steps involved in the design of an active control system are exhaustively reviewed & documented with a focus on the diesel engine noise problem. Consideration is given to the control of low frequency noise from the engine. All the noise & vibration transmission paths associated with the engine problems (engine mount, exhaust stacks & piping systems, drive shaft, mechanical couplings, airborne radiated noise) are taken into account in the review.
