Active control of a clamped L-connected plate power flow by using a piezoelectric actuator

Abstract

The dynamic response of a clamped L-connected plate and an actively controlled vibratory power flow are studied. The vibratory power flow is suppressed by a piezoelectric patch, which is bonded on the L-connected plate. The electric patch is considered as an actuator. The feedforward least mean square algorithm is used to deduce the optimal piezoelectric patch control moment. Actuator operation with close-to-optimal moments is studied with allowance for the presence of in-plane waves.
