In order to solve the fusion estimation problem of multi-sensor with unknown cross-covariance, an improved suboptimal fusion algorithm weighted by matrices is proposed for nonlinear systems. Firstly, for significance of linear minimum variance, the simplest constraints based on fusionweighted by matrices are derived by Shure complement theorem. These constraints can ensure the positive definiteness of the fusion estimate error covariance, and the consistency of the proposed suboptimalfusion estimation. Further, a suboptimalfusion estimation weighted by matrices is proposed based on linear matrix inequality (LMI). Considering the time-consuming problem in the optimization process of LMI algorithm and the complexity of the nonlinear system, the optimal value is obtained by the nonlinear auto-regressive neural network with exogenous input (NARX). Finally, a nonlinear suboptimal fusion algorithm weighted by matrices based on LMI and NARX is proposed in combination with the particle filter algorithm (PF).
