【摘要】：針對SINS性能測試存在指標多、不確定性等問題,提出了一種基于三級多源信息融合結構的SINS性能測試綜合評估算法。給出了包括精度測試、穩(wěn)定性測試和可靠性測試等三大性能測試指標和16個性能測試底層子指標構成的SINS性能測試指標體系,并構建SINS測試評估結構框架。利用多個專家對底層性能測試子指標進行評估給出相應性能子指標的模糊評價,并構造基本置信指派組成多個證據(jù);利用基于局部沖突分配的組合規(guī)則進行三級證據(jù)融合,得到性能測試指標的綜合評價結果。仿真實驗結果表明:與傳統(tǒng)的證據(jù)理論融合方法相比,該算法可以較為全面地很好地評估SINS性能,而且結果更為合理。
[Abstract]:In order to solve the problems of multiple indexes and uncertainty in SINS performance testing, a comprehensive evaluation algorithm for SINS performance testing based on three-level multi-source information fusion structure is proposed. The performance test index system of SINS including precision test, stability test and reliability test is presented, and the SINS performance evaluation framework is constructed. The fuzzy evaluation of the underlying performance sub-index is given by using multiple experts, and the basic confidence assignment is constructed to form multiple evidences, and the combination rule based on local conflict assignment is used for the three-level evidence fusion. The comprehensive evaluation results of the performance test index are obtained. The simulation results show that compared with the traditional evidence theory fusion method, the proposed algorithm can evaluate the performance of SINS well, and the results are more reasonable.
