ON INTELLIGENT ADAPTIVE CONTROL OF A TYPE SPACECRAFT

针对现代航天器对控制任务的需求特点，基于航天器对象特征模型知识描述，提出了具有多层结构的智能自适应控制系统概念。作为本方法的原理基础，分别给出了关于一类高阶对象的低阶时变等效模型的定理及其推论；以及广义补偿基本定理及其推论；然后介绍智能自适应控制器三个层次的基本设计要点。最后对带有太阳帆板展开的航天器姿态控制进行了仿真研究，结果初步表明本智能自适应控制方法的有效性。

According to the requirements of modern spacecraft control,this paper presents a hierarchical intelligent adaptive control system based on the description of plant feature model knowledge.First,the theorem on the equivalent low order time variable model of high order plant and the theorem on general PD feedback compensation are derived.Then the basic design method of the hierarchical intellitgent adaptive controller is introduced.Finally,the intelligent adaptive control method is applied to attitude control of a type spacecraft with deploying the solar panels.The simulation result shows that the intelligent adaptive control method presented is effective and feasible.
