摘    要:将分布的压电传感器/驱动器运用于智能板结构的主动减振控制中,分布的压电传感器能感知结构的局部应变状态,并通过控制回路反馈给驱动元件,构成闭环控制。建立了智能板闭环控制的分析模型,揭示在应变率反馈下,主动控制的机理是增加了结构的阻尼。用两对压电陶瓷元件仿真了柔性板的闭环控制,获得了令人满意的结果。

关 键 词:振动控制  闭环回路  压电陶瓷元件  智能板

Abstract:The distributed piezoelectric sensors/actuators are utilized for active control of vibration suppression of a plate structure in the paper. The sensors sense the local strains of the structure, feedback them to the collocated actuators through the control laws and form a close control loop. An analysis model of a smart plate is formulated using the finite element method. It is found that the mechanism of the active control is to add damping to the structure. The effect of such a closed loop control on vibration suppression of a plate is investigated by simulation. Satisfactory results are achieved.
Keywords:active control  closed  loop  piezoelectric ceramic units  intelligent plate
