Survivability of naval platforms in an important componenet in maintaining sea control and undersea superiority. Ship silencing efforts enhance survivability by reducing acoustic signatures. Active noise control provides an approach to signature reduction that can complement other means. This approach generally requires the use of multiple sensors to observe the surface response and multiple actuators to null the noise. An active control system therefore involves not only a complex structural system but also a complex controller. Design of an active control system for ship silencing applications requires information derived from structural acoustics models and/or measurements as well as methods to incorporate this information into a controller design. The purpose of the proposed Phase I study is to develop an efficient design procedure and design environment in which tools can be used to develop active noise control systems and solutions.
