【摘要】 使用同步扰动算法设计多通道有源噪声控制(ANC)系统。同步扰动算法无需对次路径建模,因此,对次路径的变化不敏感。在多通道前馈结构中使用该算法进行仿真研究。仿真结果表明,多通道有源噪声控制系统采用无模型技术是有效的。更多还原

【Abstract】 Multi-channel active noise control system using Simultaneous perturbation algorithm is considered.Simultaneous perturbation algorithm does not need to model the secondary acoustic path.It is insensitive to the change of secondary acoustic path.Simulation used the algorithm on a multi-channel feedforward structure is carried out.The simulation result shows that model-free technique is effective on multi-channel active noise control system.更多还原
