The practical application of active noise control system, using the FxLMS algorithms need to get the transfer function of the secondary path. In the past the second path transfer function is mostly obtained from an off-line identification, but taking into account the system has the change situation occurrence, the transfer function of the secondary path which the off-line identification obtain can become inaccurate. Therefore require the development of online secondary path modeling methods to solve this problem. This study proposes a new online secondary path modeling method applied optimal variable step size NLMS algorithm is at the controller and discriminator to enhance the convergence speed and performance of the online secondary path modeling in active noise control system, and use the compensator compensates interference for the identification process to improve the accuracy of the identification of the secondary path modeling. In the computer simulation with the existing methods and simulation changes, such as the secondary path change and the primary path, the secondary path at the same time change from the simulation results that the proposed method has better performance and robustness.
