Applicability of Two Kinds of H_∞ Filtering Algorithm to SINS/GPS Integrated Navigation System

In view of the applicability of H∞ robust filtering algorithms to the designed SINS/GPS integrated navigation system,both of the H∞ center filter and the H∞ posteriori filter are applied to an open-loop SINS/GPS integrated system and an closed-loop SINS/GPS integrated system respectively.The simulation results show that the H∞ center filter is applicable to the open-loop SINS/GPS integrated system,while the H∞ posteriori filter is applicable to the closed-loop SINS/GPS integrated system.This conclusion can be a reference for selecting right filtering algorithms in SINS/GPS integrated navigation system.
