Abstract
This study has been motivated by the need to control noise in naval vessels in order to reduce their detectability and hence vulnerability to enemy attack. In this report, a detailed review of controller technologies and algorithms that could be used for active noise, vibration and structural acoustic control in ship structures has been provided. The review focused on a wide range of controller technologies, methodologies and algorithms such as feedforward 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 have been exhaustively reviewed and documented. The diesel engine noise problem was the focus of the study and consideration was given to the control of low frequency noise from the engine. All the noise and vibration transmission paths associated with the engine problems namely, the engine mount, the exhaust stacks and piping systems, the drive shaft, the mechanical couplings and the airborne radiated noise have been considered in the review.
