有源结构声辐射自适应控制系统的一种新算法

A New Adaptive Algorithm for Active Structure Acoustic Control System

提出了一种适用于有源结构声辐射自适应控制系统的新算法，它直接利用传感器拾取的干扰信号和误差信号实时地建立系统模型和误差通道模型，通过解Ｄｉｏｐｈａｎｔｉｎｅ方程得到自适应控制模型，仿真表明新算法较传统的ＦｉｌｔｅｒＸＬＭＳ等算法具有更好的收敛性．

This paper develops a new adaptive algorithm for active structure acoustic control system, in which the suitable plant and system models are generated directly using the error signal and a suitable disturbance model is obtained from the measured disturbance signal. The new algorithm reaches the controller's model through solving a Diophantine equation simulations show that the proposed algorithm has a better convergence speed than the well known filter XLMS algorithm.
