| 摘 要： | 给出了带有多个挠性附件的充液飞行器的动力学方程,针对此模型采用变结构控制方法设计了系统的控制器。控制任务包括操纵天线使之跟踪事先给定的运动规律,并保持星体在惯性空间稳定,同时有效地抑制附件的弹性振动。通过仿真算例验证了此控制律的有效性。

| Abstract: | Dynamics equations are given for liquid-filled spacecraft with several flexible appendages, and a controller is designed using the variable structure control strategy. The control mission consists of maneuvering the large antennas to track the pre-selected motion laws, stabilizing the satellite in an inertial space and sup- pressing the elastic vibration of the appendages. A numerical example is given to prove the validity of the con- trol laws. |
