摘要
本文首先给出了充液中心刚体上铰接有多个挠性附件的开链多体系统的简化动力学方程 ,并以跟踪与数据中继卫星为例 ,用变结构控制方法设计了系统的控制器。控制任务是驱动单址天线使之精确地跟踪期望的运动规律 ,同时保持星体稳定 ,并且有效地抑制弹性附件的振动。
The simplified dynamical model is first presented for a open chain multi body system consisting of a liquid filled rigid platform and a number of flexible appendages.Taking Tracking and Data Relay Satellite for example,the controller is designed using variable structure control theory.The mission is to drive the single address antennas to track expected moving law,stabilize the platform synchronously,and restrain the elastic vibrating of the flexible appendages effectively.A numerical example demonstrates the effectiveness of the control law.
