Real time control prototyping system for acoustic and vibration applications

在声学和振动中存在某些类别的问题，这些问题需要能够处理大量输入和输出通道上的数据的强大的实时控制系统。这是主动控制问题（其中仔细调整的干扰用于消除不必要的噪声或振动）和声场合成（其中我们试图使用一组再现扬声器在任意环境中物理再现虚拟声场）的情况。该提案由舍布鲁克大学（GAUS）的4名研究人员提交，旨在获得领先的实时控制原型系统。由于采用了新一代超高速数字处理器，拟议的系统能够“实时”处理比申请人现有系统更多的数据，这将使申请人能够解决新的和具有挑战性的研究问题，例如主动控制飞机机舱内由湍流外部气流产生的噪音，直升机传动系统引起的噪声和振动的主动控制，汽车内低频道路噪声的主动控制，或用于模拟目的的飞机机舱和驾驶舱内噪声场的合成。

There are certain classes of problems in acoustics and vibrations that require powerful real-time control systems able to process data over a large number of input and output channels. This is the case of active control problems (where carefully adjusted interference is used to cancel unwanted noise or vibration) andsound field synthesis (where we seek to physically reproduce a virtual sound field in an arbitrary environment using a set of reproduction loudspeakers). This proposal submitted by 4 researchers from the Groupe d'Acoustique de l'Université de Sherbrooke (GAUS) is to acquire a leading-edge real-time control prototypingsystem. Thanks to a new generation of extremely fast digital processors, the proposed system has the capability to process a much larger number of data in "real-time" than the system currently available to the applicants.This system will allow the applicants to tackle new and challenging research problems - such as the active control of noise in aircraft cabins generated by turbulent exterior airflow, active control of noise and vibration induced by helicopter drive train systems, active control of low frequency road noise inside automobiles or the synthesis of noise fields in aircraft cabins and cockpits for simulation purpose.
