可伸缩的

Through the characteristic parameters, the system's real-time moment of inertia is given. Then golden section adaptive control law and logic derivative control law both based on moment of inertia are designed. The two kind of control laws are combined to control the attitude of spacecraft and their simulation results are compared with the ones of PD control law which is designed based on the certainly-known system model. The results show that this adaptive control law is effective on the kind of time-variable system studied in this paper.

根据特征模型的参数推算了系统实时的转动惯量，设计了基于转动惯量的黄金分割自适应控制器和逻辑微分控制器，将这两种控制器相结合对带有可伸缩挠性附件的刚体进行姿态控制，仿真结果与基于确知系统模型所设计的变系数PD控制器相对照，表明了该自适应方法控制一类时变系统的有效性。

On the base of applied tech. and system structure, the key tech. are expressed in detail. It includes:Knowledge representation technology: it is described in two stages by "Depictive frame + Rule group"."Depictive frame" is used to reflect the factors concerning question field."Rule group" reflects the son-question in question field; knowledge management system: it is made up of knowledge-base editing component, factor classifying component, knowledge inspecting component and extractive knowledge component; uncertainty reasoning adopt method of elicitation search strategy and data drive controlled by member knowledge. It take reliability of compound proof at first. That can resolve the matching contradiction. Reasoning explanation introduce pre-text and followed method of resolving path. Knowledge discovery component take SLIQ as basic arithmetic. It provides classification model in two stage forms which aim at training suit. That is decision tree and productive rule.

在确定应用技术与系统结构的基础上，重点阐述了本文的核心技术，这包括：知识表示技术，采用"描述框架+规则组"的层次结构，"描述框架"用于描述问题域所涉及的因素，"规则组"反映问题域内的子问题；知识管理系统，由知识库编辑构件、因素分类构件、知识检测构件和知识求精构件组成；不确定性推理机采用启发式搜索策略，元知识控制的数据驱动，以复合证据可信度优先作为匹配冲突消解的策略，推理解释采用预置文本与求解路径追踪的方法；知识发现，采用SLIQ快速可伸缩算法，分类模型用判定树与产生式规则两种形式描述。
