Novel Remote Sensing Strategies for the Active Control of Sound Radiation

主动结构声控制系统目前使用结构上的加速度计来推断远场辐射压力的信息。然而，这种系统需要一个初步的校准阶段，这将需要在远场位置进行一系列声学测量。该项目将研究新的传感策略，避免需要这个复杂的校准阶段。特别是，该项目将研究基于光学、声学和结构测量的各种先进传感技术。开发的传感策略最终将集成到一个实际的主动控制系统中，其性能将通过现实世界的实验试验进行验证。该项目由大型工业合作伙伴支持，为成功的候选人提供了广泛的潜在机会。特别是，强大的工业联系有助于确保研究将对现实世界的工程产生直接影响

Active structural acoustic control systems currently use accelerometers on the structure to infer information about the far-field radiated pressure. However, such systems require a preliminary calibration phase that would require a series of acoustic measurements at far-field locations. This project will investigate novel sensing strategies that avoid the need for this complex calibration phase. In particular, the project will investigate a variety of advanced sensing technologies that are based on optical, acoustical and structural measurements. The developed sensing strategies will ultimately be integrated within a practical active control system and the performance will be validated through real-world experimental trials.This project is supported by a large industrial collaborator, which provides a wide range of potential opportunities for the successful candidate. In particular, the strong industrial connection helps to ensure that the research will have a direct impact on real-world engineering
