A Robust SINS/VO Integrated Navigation Algorithm Based on RHCKF for Unmanned Ground Vehicles
IEEE Access, 2018 High precision localization information is the precondition of unmanned ground vehicles. But the global navigation satellite system (GNSS) signal turns unreliable in urban and forest areas since it is blocked by buildings and trees easily, which causes ...

Fuzzy Consensus Cubature Information Filtering for Space Target Tracking
International Journal of Aerospace EngineeringA fuzzy distributed nonlinear state estimation issue on the possibilistic framework is investigated in this paper. Firstly, unlike the Gaussian probability distributions on the traditional probability framework, the noises are modeled as fuzzy random variables (FRVs) with trapezoidal possibility distributions (TPDs), and then a fuzzy cubature paradigm ...
