Active noise control system for automobiles based on adaptive and robust control

Shuichi Adachi, Hisashi Sano

Open publisher page 7 citations

Abstract

An active noise control (ANC) problem, especially for active control of road noise inside automobiles, is presented. First, a model for an acoustic field, which includes loudspeaker and microphone characteristics, is constructed using the system identification theory. Next, the control law of a two-degree-of-freedom ANC (2-DOF ANC) system is designed based on the identified model. Finally, the control performance of the 2DOF ANC system is examined through computer simulations using actual vehicle data measured in the experiment which simulates road noise within the cabin.
