摘　　要：为了对发动机排气噪声进行实时控制,分析了发动机排气噪声产生的机理、噪声频谱特征,并利用基于自适应算法的有源消声控制技术对发动机排气噪声进行了实时控制分析实验．实验结果表明,所采用的自适应有源消声控制技术能够实时地对排气噪声进行控制．For controlling the engine exhaust noise at real time on line, the source, transmit mechanism and the spectrum character of the diesel exhaust noise were analysed. By using adaptive control technique of active noise, some experiments are designed to control exhaust noise of diesel. Experiment results show that exhaust noise of a diesel could be attenuated and our adaptive control technology of active noise could control diesel exhaust noise at real time on line.
