摘要: 针对对地观测卫星姿态控制系统 ,着重考虑干扰、噪声对卫星姿态稳定度的影响。忽略耦合和挠性部件影响 ,也不考虑敏感器和执行机构的动态特性 ,针对卫星定向模式的主调节器设计问题构造了一种简单实用的非线性控制器 ,并分析和验证了该非线性控制器的有效性。

Abstract: A simple and efficient nonlinear controller on the Attitude Control System (ACS) onboard Earth Observation Satellites (EOS) is described. The control problems are mainly about the influence of the pointing stability from the disturbances and measurement noises, without considering the behavior of sensors and actuators. The performances of the nonlinear control system are checked by extensive simulations.
