The invention relates to a spacecraft three-super control robust adaptive multistage cooperation method, which is suitable for astronomical observation and other large satellite platforms with ultrahigh precision, ultrahigh stability and ultrahigh agility for payload attitudes. Different from a traditional PID control algorithm, the robustness characteristic of sliding mode control on a sliding mode surface and the characteristic that self-adaptive control can estimate parameters on line are combined, and star-active pointing ultra-quiet platform two-stage composite control is carried out. Themulti-stage cooperative control thought comprises the steps that (1) an active pointing ultra-static platform is installed between a load and a spacecraft body, and control parameters of the active pointing ultra-static platform are designed according to the quality characteristics of the spacecraft body and the load; and 2) a star robust adaptive controller considering bandwidth constraints is designed by combining ideas of sliding mode control and adaptive control, so that the star controller can be matched with the active pointing ultra-quiet platform to realize three-override control of the load.

    一种航天器三超控制鲁棒自适应多级协同方法,适用于天文观测等对有效载荷姿态具有超高精度、超高稳定度和超高敏捷度的大型卫星平台。与传统的PID控制算法不同,本发明结合滑模控制在滑模面上的鲁棒性特点和自适应控制能够在线估计参数的特点,进行星体‑主动指向超静平台两级复合控制。多级协同控制思路为:1)在载荷和航天器本体之间安装主动指向超静平台,根据航天器本体和载荷的质量特性设计主动指向超静平台的控制参数;2)结合滑模控制和自适应控制的思想,设计考虑带宽约束的星体鲁棒自适应控制器,使得星体控制器能够与主动指向超静平台相匹配,实现对载荷的三超控制。
