| 摘 要： | 利用双线性滤波器对非线性信号处理方面的优势,同时结合李雅普诺夫稳定性理论,提出BF-LMS算法。该算法首先定义李雅普诺夫函数,然后对双线性滤波器的权系数进行自适应调整,并且根据李雅普诺夫稳定性理论,使误差渐近趋近于零,从而达到能够避免传统噪声控制方法中对噪声信号统计特性的依赖性,最终使系统达到渐近稳定。

| Abstract: | Utilizing the benefits of the adaptive bilinear on nonlinear signal processing,and applies the Lyapunov stability theory into the active noise control system,the BF-LMS algorithm is proposed.Unlike the traditional FXLMS algorithm using gradient theory,a Lyapunov function of the tracking error is defined,and tracking error converges to zero asymptotically by adjusting the adaptive output error bilinear filter coefficient. |
