中文摘要：

针对带有挠性太阳帆板卫星的姿态控制问题，设计了基于支持向量机的逆模型控制律，采用模态分析方法对姿态模型进行简化处理；首先设计了基于支持向量机的恒衰减因子逆模型控制律，分别在无干扰、阶跃干扰和周期性干扰三种情况下进行仿真；考虑执行机构的力矩输出有限，在对恒衰减因子取不同值下的仿真结果进行分析的基础上，又分别设计了衰减因子取分段函数形式及输入限幅的控制律；仿真结果显示，设计的控制律能够使系统具有好的稳定效果和动态品质，有效地减小了挠性模态振动对姿态控制的影响，并对扰动具有一定的抑制能力。

英文摘要：

An inverse model control law based on SVM is designed for the attitude control of satellite with solar arrays. The satellite model is simplified by using modal analysis. An inverse model controller with constant attenuation factor is proposed, the simulation results with different disturbance is presented. Because the torque is limited, the controller is implemented with piecewise control function and limited amplitude control law in view of simulation results with various attenuation factors. Simulation shows that the affection of flexural mode on the attitude of satellite can be reduced greatly and the disturbance can also be restrained.
