摘要：

Recent development of large and flexible structural systems has emphasised the importance of distributed structural identification and vibration control of these high-performance distributed parameter systems (DPSs). In this paper, distributed piezoelectric sensors and actuators are used for structural identification and vibration control of DPSs. The distributed piezoelectric layers can respond to structural oscillation and generate output voltages due to the direct piezoelectric effect; and they can also separately produce control forces/moments due to the converse piezoelectric effect. An improved piezoelectric finite element with internal degree of freedom is first formulated. Then structural identification and control using the piezoelectric finite element is derived. State variable transformation of the dynamic equation is also presented. Distributed structural identification and control of DPSs are studied using theoretical, experimental, and finite element techniques. © 1991.
