Study on Mechanism Control of Solar Wing in Space Station Base on Ruled Inference

针对空间站上使用的太阳翼展开流程复杂的问题,提出一种基于规则推理技术的太阳翼展开流程控制方案:运用Rete算法设计了太阳翼展收控制推理系统,给出了空间站太阳翼按程序展开流程策略库设计方法,并根据按程序展开工况构造模拟事实序列来验证规则推理系统对于展收流程控制的正确性。仿真结果表明,规则推理技术可以有效的完成空间站太阳翼机构展收流程控制工作。

To deal with the problem that the deployment process of the solar wing of the space stationis too complicated,a process control method based on ruled inference technology was proposed.A solar wing control inference system using Rete algorithm was designed and implemented,its structureand operation principles were introduced,and the data type of Fact,Event,Expression andRule were defined.Then a design schema of solar wing deployment program strategy library forspace station was introduced and a simulation fact sequence according to the programmed-deploymentcondition was constructed to verify the correctness of the deployment process control using therule inference system.The results verified the effectiveness of the process control method for the solarwing of the space station.
