Abstract:
Due to their low computational complexity, reduced wiring cost, and flexibility of scaling up, decentralized multiple channel active control systems are attractive in many applications. In a decentralized multiple channel active control system, a number of small subsystems are constructed, which are updated independently with only the associated error signals. In this letter, a time domain two channel decentralized control algorithm is proposed to achieve the similar noise reduction performance as the centralized one. Auxiliary filters are introduced to filter the reference signal for control filter update and a unique design method is proposed to shape the frequency response of the auxiliary filters. The simulation results using the measured impulse responses demonstrate the efficacy of the proposed algorithm for broadband noise control.
