| Abstract: | Using the direct proportional feedback control,active vibration control equations are derived from the dynamic equations of linear elastic piezoelectric laminated structure.Piezoelectric actuator/sensor are modeled by the three-dimension eight-node coupled element.The host structure is modeled by the three-dimension eight-node element.The finite element model of piezoelectric smart structure has been developed by use of ANSYS/APDL parameter language.The optimal actuator/sensor location problem is formulated... |
