| 摘 要： | 介绍了发动机排气噪声自适应控制系统的工作原理，并建立了系统模型，对以振动信号作为参考信号的消声效果进行了仿真，并且将发动机机体上不同点的振动信号作为参考输入进行了消声效果的比较．结果表明：当选取振动信号作为参考信号时，不仅要考虑振动信号与排气噪声信号的相关性，还要考虑振动信号的能量分布．

| Abstract: | This paper analyzes the operating principles of adaptive noise control system for engine exhaust and constructs a system model, simulates the performance of AANC in which vibration signal used as the reference input, and compares the different effects with different vibration signal. The results show that when selecting vibration signals as reference signals, the selection of reference signal depends not only on the correlation, but also on the distribution of vibration energy. |
