压电材料作为结构振动控制中的敏感元件,其在智能结构中的应用是一个重要的研究方向。在使用压电材料作为传感器和作动器的条件下,本研究采用了两种控制算法对悬臂梁进行振动控制试验研究。结合根轨迹结合分析,快速确定结构的控制增益,得到了系统稳定的良好结果。同时,利用模态控制方法进行处理,有效地控制了结构响应。试验结果表明,两种控制方法均可增加系统阻尼,减小系统稳定时间,效果较好。
As a sensitive element in vibration control of structures, the application of piezoelectric materials in intelligent structures is an important research direction. Under the condition of using piezoelectric materials as sensors and actuators, two control algorithms are used to control the vibration of cantilever. Combined with root locus analysis, the control gain of the structure is quickly determined, and the good result of the system stability is obtained. At the same time, the use of modal control method for processing, effectively control the structure of the response. The experimental results show that the two control methods can increase the system damping, reduce the system settling time, the effect is better.
