Abstract

The influence of directional piezoelectric actuation (d sub 31 not = d sub 32 ), and isotropic piezoelectric actuation (d sub 31 = d sub 32 ) on static deflection and control behaviour of aluminium panels is evaluated through numerical experiments. A four-node Piezo-Elastic field consistent plate element based on Mindlin-Reissner theory is developed and the finite element procedure is implemented in MATLAB platform. An active control scheme using Linear Quadratic Regulator is adopted in modal domain for the first mode control. The control analysis shows that the actuator efficiency is significantly modified with boundary effects. The directional actuation that actually represents the piezoelectric anisotropy has a better control performance compared to isotropic actuation. The results of the control study clearly indicate that if the d sub 32 - based actuation effect is minimised then better control can be achieved.
