摘要
提出了一种前反馈混合的响度控制有源消声系统,其前馈部分采用响度控制有源消声算法,反馈部分引入μ综合鲁棒控制。建立反馈有源消声的μ综合控制框架,以轿车封闭车厢为对象,设计双通道反馈有源消声μ综合鲁棒控制器。对前反馈混合控制和单一前馈控制进行有源消声对比试验,结果表明,混合控制的控制效果和鲁棒性都优于单一的前馈控制。
A hybrid feedforward-feedback loudness-based active noise control （ANC） system is proposed, in which active loudness control algorithm is used in feedforward part and μ synthesis robust control is introduced in feedback part. The μ synthesis control framework for feedback ANC is established and aμ synthesis robust controller for two-channel feedback ANC for an enclosed car cabin is designed. An ANC comparative test between hybrid feed- forward-feedback control and sole feedforward control is conducted. The results indicate that hybrid feedfoward-feed- back control is superior to sole feedforward control in both control effects and robustness.
