基于模糊理论的卫星天线双轴驱动机构效能评估

The Synthetic Effectiveness Evaluation of the Two-axes-position Mechanism for Satellite Antenna based on the Fuzzy Theory

根据卫星双轴驱动机构的组成及功能,建立了双轴驱动机构综合效能评价指标体系,以某型卫星天线双轴驱动机构为研究对象,运用层次分析法和基于模糊理论的定性与定量相结合评估指标量化的方法,建立了多级模糊综合评价模型,并利用实例说明了评估方法和过程,结果表明该机构的综合效能良好。

Based on the constitution and function of the two-axes-position mechanism for satellite antenna,a set of index system of effectiveness evaluation is proposed.Taking the two-axes-position mechanism for satellite antenna as the study object,a multi-stage fuzzy combined evaluation model is established by means of AHP and the evaluation method of combined qualitative analysis with quantitative count based on the fuzzy theory,and the detailed descriptions of each step are elaborated by a pragmatic example.The result indicated that the synthetic effectiveness of this the two-axes-position mechanism for satellite antenna was good.
