摘要
从压电材料的驱动原理出发 ,将压电驱动器对梁的作用 ,在压电片两端点处的梁截面中点 ,等效为一对平衡力和一对平衡力偶 ,然后采用频响应函数进行驱动器位置优化 ,并采用模态空间控制方法对智能悬臂梁的振动进行了主动控制 。
Based on the research of piezoelectric actuator, the optimized collocation of actuators is studied Moreover a mode control means is presented, and based on the means an experiment on the vibration control of a cantilever beam with collocated piezoelectric sensors and actuators is carried out In the experiment, the vibration of the beam is controlled effectively
