摘要
本文研究了压电智能梁振动控制中压电传感作动元件的优化设计,并考虑了控制增益和结构阻尼的影响。采用负速度反馈控制策略及等效阻尼比优化准则。对简支梁和悬臂梁采用遍历搜索的方法计算了不同增益和结构阻尼下的优化,结果对进一步研究优化设计和振动控制有一定的参考价值。
In this paper, the optimization of placement and size of piezoelectric actuator/sensor in the vibration control for a piezoelectric beam is studied and the control parameter and structural damping parameter are considered integrally. The negative-velocity feedback strategy and the optimization criterion of equivalent damping ratio are adopted. The optimization procedure is carried out for a simple-supported beam and a cantilever beam by using the numerical searching method in the case of different control gain and structural damping. The result is available for the further study on the optimal design and vibration control.
