This paper aims at characters of aerospace flexible structure vibration response such as light dump, multimode and low natural frequency, and focuses on adaptive vibration control algorithm and actualization solution for piezoelectric smart flexible structure. Multichannel (MIMO) adaptive filter feedforward method is used for active vibration control of the model structure with distributed-embedded piezoelectric observe and control network. Experimental process is performed on a DSP system, achieves active vibration restraint at multi-order natural resonance frequencies. The result shows it is effective to restrain structural vibration response using the algorithm and experimental system of this paper. The anti-interference also tests well.
