Abstract:
An active noise control (ANC) system uses a proportional integral (PI) controller to produce a control signal based on feedback that comprises a combination of ambient sound and antinoise. The ANC system generates a corrected control signal based on the control signal and a configurable filtering parameter, and produces the antinoise under control of the corrected control signal such that the antinoise destructively interferes with frequencies of the ambient sound to produce the feedback. The ANC system uses a microphone to receive the feedback and provide the feedback to the PI controller.
