Active control of composite plates with integrated piezoelectric sensors and actuators under various dynamic loading conditions

Theoretical formulations based on the classical laminated plate theory (CLPT) and Navier solutions are presented for the analysis of laminated composite plates with integrated sensors and actuators and subjected to both mechanical and electrical loadings. A negative force-cum-moment feedback control algorithm coupling the direct and inverse piezoelectric effects is presented and used as an active control of the dynamic response of the integrated plate structures through closed loop control. Emphasis in this study is also given to different types of dynamic loading condition. Three types of loading condition are considered, namely, an initial displacement being applied to the plate, harmonic surface loading and the plate being subjected to a moving point load.
