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的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,这样的控制规律能有效地抑制帆板的振动。
This paper makes a study of the solar panels of the flexible spacecraft and establishes the system dynamics model. A sliding mode variable structure control law is used to control the vibration of solar panels. At the same time SMA wires are embedded into solar panels and the classical linear optimal control is used to control the SMA drive. The simulation results show that such a control law suppresses the vibration of the panels effectively.
