摘要：

Facing the background of active vibration control of large flexible space structures, a multi-input multi-output(MIMO)active vibration controller was analyzed and implemented based on filtered-U least mean square(FULMS)algorithm. It could solve the problem that the reference signal of filtered-X least mean square(FXLMS)algorithm can not be extracted from the vibration response of the controlled structure. By analyzing FULMS algorithm and the basic control process briefly, simulations of FXLMS and FULMS algorithm were done respectively while the exciting signal was picked as the reference signal and the reference signal was extracted from controlled beam. Taking the configured piezoelectric beam as research object, FULMS control experiment was done on the vibration control platform. Both simulation and actual experiment results show that the designed MIMO FULMS algorithm based vibration controller has a good control performance, with rapid convergence, and it could extract reference signal from vibration response of the controlled structure directly.
