摘要
由于管道有源消声系统的参数时变性和本质非线性,基于传统自适应算法的控制系统稳定性不够,容易产生振荡.文章采用神经网络BP算法,利用Matlab6.0建立了管道有源消声的仿真控制系统.通过与采用传统自适应算法的控制系统进行仿真研究对比,证明采用神经网络BP算法的控制系统消声效果更加明显.
The stability of the controller based on traditional adaptive algorithms is not sufficient because of the time-varying parameters and essential nonlinear property of the active noise control system in ducts. The neural network BP algorithm is applied to the active noise control system in ducts, and the simulation research is carried out by means of matlab6.0. The results show that the perfor-(mance) of the controller using BP algorithm is superior to the one using traditional algorithms.
