| 摘 要： | 针对自适应IIR滤波器算法容易陷入局部极小点的缺陷,提出了一种新的自适应递归滤波辨识算法.该算法采用模型参考自适应系统设计了辨识参数自适应律,基于Lyapunov理论保证了自适应递归算法的稳定性,而且辨识参数收敛.仿真结果表明了该算法的可行性和滤波器结构的正确性.

| Abstract: | Adaptive IIR filtering suffers from potential instability and converges to a local minimum of the objective function.According to these problems,on the basis of model reference adaptive system,a new adaptive recursive filters identification algorithm is proposed.Based on the Lyapunov theory,this algorithm is stable and parameters are convergent.Simulations that confirm the utility of the new algorithm are included. |
