摘要
针对当前汽车噪声主动控制系统只能处理单一噪声源的问题,提出一种多源噪声主动控制方法,并构建了相应的多通道噪声主动控制系统。首先,以路噪和发动机噪声作为降噪目标,随后采用多源Fx-LMS算法实现目标噪声的抵消。相对于传统的噪声主动控制方法,该方法在多源噪声匹配和降噪方面表现更优,应用于实车的噪声主动控制中,实现了宽带路噪和窄带发动机噪声的同步消减。
Since the current active vehicle noise control system can only handle a single noise source,a multi-source active noise control method is proposed,and a corresponding multi-channel active noise control system is constructed.Firstly,road noise and engine noise are taken as the noise reduction targets,and then the multi-source FxLMS algorithm is used to cancel the target noise.Compared with the traditional active noise control methods,this method has better performance in multi-source noise matching and noise reduction.When applied to the active noise control of actual vehicles,it realizes the simultaneous reduction of broadband road noise and narrowband engine noise.
