摘要

Multiple-model approach is one of the main streams for hybrid estimation. The difficulty of thisapproach to estimate the hybrid state of the semi-ballistic reentry vehicle (SBRV) is model-set design. This paperproposes a quasi-Monte Carlo model set that can ensure the estimator near-optimal in the sense of minimummean square error (MMSE). The SBRV has a high nonlinearity and its mode is spanned by multiple parameterswith known bounds. The design methods and characteristics of the quasi-Monte Carlo model set are given.The proposed model set has a higher accuracy than the model-set generated by the Monte Carlo method. Thetheoretical analysis and simulation results show the effectiveness and reasonability of the newly designed modelset.
