摘要
Abstract
The cluster control system, which is made up of several small scale multichannel centralized systems, can balance the complexity and risk of instability between centralized and decentralized systems. In this study, the theoretical analysis for active control of tonal noise in the enclosure is carried out, and the steady state error and the stable condition are obtained. Finally, experiments on active tonal noise control in a helicopter cabin are performed. It is shown that the equivalent noise reduction of the cluster control system is consistent with that of the centralized system, but its stability is better than that of the decentralized system.关键词
