Abstract
Decentralized multi-channel active vibration control(DMCAVC)offers distinct advantages including computational efficiency and configuration flexibility.However,traditional decentralized multi-channel control systems often fail to guarantee sta-bility due to their partial disregard for structural dynamic characteristics,resulting in an inherent trade-off between system stability and control performance.Based on stability analysis of DMCAVC systems,an enhanced decentralized multi-channel control algo-rithm was proposed,and the improved vibration suppression capability was demonstrated by means of comparative simulaltion.The results show that the proposed algorithm achieves real-time estimation and dynamic optimization of limiting parameters,enabling the decentralized control system to optimally balance vibration suppression and stability.The vibration response of the structures with abrupt changes in the secondary channel characteristics is effectively suppressed,and the vibration response amplitudes of the two channels are reduced to 11.8%and 24.9%of the pre-control levels.关键词
