摘　　要：针对FXRLS算法在收敛速度上优于FXLMS算法,但其计算量大的问题,利用快速横向滤波器原理改进FXRLS算法,推导得出FT-FXRLS算法.并进行了仿真分析.搭建实验台架,对该算法进行实验研究.结果表明:在仿真条件下振动加速度可降低41.5和42.6 dB,在实验条件下分别可降低39.1,42.1,28.3,23.3 dB.Aiming at the problem that FXRLS algorithm is superior to FXRLS algorithm in convergence speed,but its computation is large,the FXRLS algorithm was improved by using the principle of fast transversal filter,and the FT-FXRLS algorithm was deduced and simulated.The algorithm was experimentally studied by building an experimental bench.The results show that the vibration acceleration can be reduced by 41.5 and 42.6 dB under simulation conditions,and 39.1,42.1,28.3 and 23.3 dB respectively under experimental conditions.
