摘要
文章围绕智能结构水下振动控制中传感器/作动器的位置优化问题,搭建Abaqus-Matlab联合建模平台,得到水下智能结构的状态空间模型,建立基于能量传递的优化准则,在频段为0～600 Hz处,对比可选传感器及作动器位置区域的可控、可观度的大小,由此获得了传感器/作动器的最佳粘贴位置。最后通过相同激励信号下,不同配置位置的水下压电智能圆柱壳振动能量传递的大小,验证了优选位置的合理性。
This paper mainly focuses on the problems of the optimal placement of sensor and actuators for vibration control of underwater intelligent structure.The combined modeling platform with Abaqus and Matlab are established to obtain the optimal state-space model of underwater intelligent structure.And based on the energy transform,the optimal placement criterion of sensor and actuators is obtained by the use of optimal model.Adopting the optimal placement criterion,the observability/controllability of optimal sensor and actuators for advanced intelligent structure are computed on selected location and then the best bonded position of sensor and actuators is gotten at 0~600 Hz.Finally,with the same excited signal,the rationality of optimal position is verified by the different voltage responses with different bonded position in the water.
