Abstract
In this paper, the principle of H ∞ filtering is discussed and H ∞ filter is constructed, which is used in the initial alignment of the strapdown inertial navigation systems (SINS). The error model of SINS is derived. By utilizing constructed H ∞ filter, the filtering calculation to that system has been conducted. The simulation results of the misalignment angle are given under the condition of unknown noises. The results show that the process of alignment with H ∞ filter is much faster and with excellent robustness.
