【摘要】 采用压电陶瓷片作为传感器和执行器对柔性梁振动进行传感和控制，分析了振动传感和能量消耗控制方法的原理．并根据实际情况对传感信号进行了必要的处理以保证控制的稳定性和有效性．从实验结果来看，达到了比较明显的减振效果，为今后深入研究太空机敏柔性结构的振动主动控制奠定了良好的基础。更多还原

【Abstract】 Piezoelectric patches as sensor and actuator are used for active vibration control of flexible beam and the principle of vibration sense and energy exhaust control method are analyzed. The processing for signal of sense has been done for reliable and valuable controls. And the control experiment show a good result. This builds the better foundation for the deep research of the active vibration control of outer space smart flexible structures.更多还原
