Performance Analysis and Comparison of FXLMS and FULMS Algorithm for Active Structure Vibration Control
Taking the piezoelectric beam as research object,filtered-U least mean square (FULMS) control algorithm for feed-forward adaptive control is analyzed and compared with filtered-x least mean square (FXLMS) feed-forward control algorithm,which can solve the problem that the vibration feedback may affect the measuring of the reference signal in FXLMS.By introducing FXLMS and FULMS control algorithm,this paper gives the controller design structure,while structure modal analysis to determine the optimal placement of piezoelectric sensors and actuators and model parameter identification for the controlled structure are done.Then the active vibration control experimental platform is established to verify the effectiveness of FULMS control scheme as well as FXLMS control scheme.Meanwhile the experimental results of FXLMS and FULMS are compared.The performance comparison shows that the FULMS adaptive vibration controller has a better control performance,with more rapid convergence than FXLMS controller.
