柔性结构的载荷识别

Load Identification of Flexible Structures

作为动力学逆问题的载荷识别一直是科技与工程领域关注的课题。选择柔性悬臂梁为对象,开展载荷识别与主动控制问题的研究,给出一种基于变结构控制算法的载荷识别方法和控制律的设计方法。研究结果显示,所给方法能够有效地辨识出结构所受到的外部载荷,变结构控制律能够有效地抑制梁的弹性振动。

Load identification, as an inverse problem of dynamics, is an attractive technical problem in engineering. In this paper, the load identification and active control for a flexible cantilever beam was studied. An identification method and a controller design method based on the variable structure control (VSC) algorithm were presented. Simulation results indicate that the presented identification method is effective in identifying the external load of the beam and the designed controller is available for vibration control of the beam.
