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Ｄｉｏｐｈａｎｔｉｎｅ方程得到自适应控制模型，仿真表明新算法较传统的ＦｉｌｔｅｒＸＬＭＳ等算法具有更好的收敛性． A new algorithm for adaptive structure control of acoustic radiation in active structures is proposed. The system model and error channel model are established by using the disturbance signals and error signals picked up by the sensors directly. The Diophantine equation is adaptively controlled The simulation results show that the new algorithm has better convergence than the traditional algorithm such as FilterXLMS.
