中文摘要	卫星姿态动力学系统与其线性化模型之间的误差会影响姿态控制的精度。应用多层前馈网络对该误差进行建模,并基于此模型和线性系统理论设计了一种新型的卫星姿态控制器,该控制器实现了卫星三轴解耦控制,并使卫星姿态动力系统与其线性化模型的响应误差在最小二乘准则意义下最小。仿真结果表明在俯仰角、滚动角和偏航角机动量均为0.01rad情况下,控制器能够提供较高的控制精度。; The error between satellite attitude dynamics and its linearized model can affect the attitude control precision. The model of the error was established with a multilayer feedforward network, and a new controller based on the model and linear control theory was presented. The controller realizes the decoupled control of the satellite attitude and minimizes the state response error between satellite attitude dynamics and its linearized model in the sense of the least square criterion. Simulation results show that the control precision is high when the maneuvering angles of pitching angle, roll angle and yaw angle are all 0.01 rad.
