| Abstract(in English) | Filtered-x algorithm is widely used as active noise control, however the modeling error of secondary path modeling occurs to degradation of noise reduction ability and makes the ANC unstable. In order to solve the problem, a pre-inverse type ANC with bias free adaptive algorithm is proposed in this paper. In this system, an adaptive filter estimates the inverse transfer function of secondary path and the weights of the adaptive filter are copied to the filter, which is inserted before the secondary path. Then a primary path is estimated by another adaptive filter. Therefore, the primary and secondary paths are controlled independently and the ANC improve the noise reduction ability. Unfortunately, the pre-inverse type ANC degrades the estimation accuracy of the secondary path due to bias. Thus, the bias free adaptive algorithm with square sum of the correlation is also proposed. The adaptive algorithm takes advantage of the independence between the input signal and disturbance. |
