| 摘 要： | 以挠性航天器的太阳帆板为研究对象,在建立挠性系统动力学模型的基础上,采用滑模变结构控制策略进行挠性航天器太阳帆板的振动控制,同时在帆板上植入SMA丝形成驱动器,并采用经典线性最优控制算法控制SMA驱动器。仿真结果表明,这样的控制规律有效抑制了帆板的振动。

| Abstract: | Taking flexible spacecraft with solar panels as study object,this paper established the system's dynamics model.A sliding mode variable structure control law to control the vibration of solar panels was put forward.SMA wires were embedded into solar panels,and the classical linear optimal control was used to control the SMA drive.The simulation results show the control law suppresses the vibration of the panels effectively. |
