摘要：In this paper the vibration of a smart cantilever plate is being controlled. Active vibration control (AVC) methods will be used to eliminate undesired vibrations in engineering structures. Using piezoelectric smart structures for the active vibration control for actuator and sensor in engineering applications. Simulation and experimental studies on active vibration control of smart structures have been presented. The closed loop control laws are incorporated into the finite element (FE) models by using ANSYS parametric design language (APDL). The proposed procedure is tested by active control for force vibration (harmonic excitation). The active vibration suppression is achieved using proportional gain method. Experiments have been conducted to verify the closed loop simulations. Smart plate consists of aluminum plate (250 mm x 180 mm x 0.5 mm) surface bonded piezoelectric patches of MIDÉ Quick Pack QP16n transducers (45.9 mm x 20.5 mm x 0.25 mm). Experimental results are obtained by LabVIEW programs developed in the study.
