种微小卫星控制半物理仿真系统可信度评估方法

In the development of micro-satellites，the credibility assessment of hardware-in-the-loop（HIL）simulation systems is crucial to mission decision-making and system operational reliability. However，conventional evaluation methods suffer from low accuracy in qualitative indicator quantification and unreasonable weight determination. To overcome these deficiencies，a novel credibility assessment approach based on the group analytic hierarchy process （GAHP）is proposed. The method includes two core parts. First，a semantic modeling method based on the interval type-2 fuzzy sets is adopted to achieve accurate quantification of qualitative indicators，and a defuzzification algorithm is utilized to guarantee numerical evaluation consistency. Second，Bayesian inference is applied to correct expert subjective weights and realize comprehensive weight calculation. Comparative results with the entropy weight method show a high degree of consistency in weight ranking，which verifies the correctness of the weight solving mechanism. Based on real satellite measured data，the proposed method is applied to the credibility evaluation of a laboratory satellite semi-physical simulation system. The results indicate that the presented approach can effectively evaluate the performance of satellite HIL simulation systems and provide a more accurate evaluation scheme for semi-physical simulation assessment.
