Abstract: In this paper, some fundamental problems in the vibration control of flexible structures using piezoelectric ceramics are studied. The matching relationship between piezoelectric actuators and structural matrix is analyzed. The optimal arrangement of collocated modal sensor/actuator in a flexible cantilever plate is discussed. The feasiblity is verified by experiments.
Keywords: flexible structure, piezoelectric ceramics, adaptive structure, vibration control.
