Abstract | The invention discloses a wireless active noise control system, and belongs to the technical field of active noise control. According to the invention, signal transmission is carried out in a wireless communication mode, and the difficulty in deployment and maintenance of an entity connection system is solved. For a single-channel system, under the condition that the whole wireless active noise control system is not stopped, online updating of a secondary path model is carried out by adding random noise, the accuracy of the secondary path model in each time period is ensured, and the noise reduction effect of the whole active noise control system is also ensured. Based on the existence of an upper computer, the self-adaptive iteration of the secondary path is increased without increasing the burden of a controller, the saved hardware resources can be used for increasing the coefficient length of a control filter, other parts needing to increase the system operation complexity, such as an improved algorithm wi |
