【摘要】：針對(duì)SINS性能測(cè)試存在指標(biāo)多、不確定性等問題,提出了一種基于三級(jí)多源信息融合結(jié)構(gòu)的SINS性能測(cè)試綜合評(píng)估算法。給出了包括精度測(cè)試、穩(wěn)定性測(cè)試和可靠性測(cè)試等三大性能測(cè)試指標(biāo)和16個(gè)性能測(cè)試底層子指標(biāo)構(gòu)成的SINS性能測(cè)試指標(biāo)體系,并構(gòu)建SINS測(cè)試評(píng)估結(jié)構(gòu)框架。利用多個(gè)專家對(duì)底層性能測(cè)試子指標(biāo)進(jìn)行評(píng)估給出相應(yīng)性能子指標(biāo)的模糊評(píng)價(jià),并構(gòu)造基本置信指派組成多個(gè)證據(jù);利用基于局部沖突分配的組合規(guī)則進(jìn)行三級(jí)證據(jù)融合,得到性能測(cè)試指標(biāo)的綜合評(píng)價(jià)結(jié)果。仿真實(shí)驗(yàn)結(jié)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(píng)估SINS性能,而且結(jié)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.
