Noise power scheduling in active noise control systems with online secondary path modeling
In active noise control (ANC) systems, the online secondary path modeling (OSPM) methods that use additive random noise are often applied. The additive random noise, however, contributes to the residual noise, and thus deteriorates the noise control performance of ANC systems. This paper proposes a new OSPMmethod with power scheduling of additive random noise. Here the OSPM filter is adapted us...
متن کاملA New Structure for Feedforward Active Noise Control Systems with Online Secondary-path Modeling
This paper proposes a new structure for the feedforward active noise control (ANC) systems with online secondary path modeling. The proposed structure 1) uses the same error signal for updating the noise-control process as used for the modeling process, and 2) incorporates an averaging based filtered-reference algorithm in the noise-control process. The theoretical considerations are confirmed ...
متن کاملA Robust Feedforward Active Noise Control System with a Variable Step-Size FxLMS Algorithm: Designing a New Online Secondary Path Modelling Method
Several approaches have been introduced in literature for active noise control (ANC)systems. Since Filtered-x-Least Mean Square (FxLMS) algorithm appears to be the best choice as acontroller filter. Researchers tend to improve performance of ANC systems by enhancing andmodifying this algorithm. This paper proposes a new version of FxLMS algorithm. In many ANCapplications an online secondary pat...
متن کاملA secondary path modeling technique for active noise control systems
A secondary path modeling technique for active noise control systems is developed for both on-line and off-line modeling with faster convergence and higher modeling accuracy. The optimum delay for the adaptive prediction error filter to reduce the interference in system modeling is equal to the length of the impulse response of the secondary path being modeled.
متن کاملA Technique for Active Noise Control Systems with Online Secondary Path Modeling Using Additive Noise Power Scheduling
This paper proposes a new method for online secondary path modeling (OSPM) in active noise control (ANC) systems. The proposed method comprises two adaptive filters: a noise control filter and an OSPM filter. The noise control filter is adapted by the FxLMS algorithm, and using the same error signal as used in the adaptation of the OSPM filter. The OSPM filter is adapted using a variable step s...
