  • 捷聯式慣性導航系統是一個具有自主包容性、不受天候的影響及地理環境限制的導航系統。慣性導航系統本身含有加速規和陀螺儀,可以提供載具所有導航資料:包括位置、速度和姿態(縱搖、橫搖和偏航角),其具有高度的穩定性和高精密度。

      本文對慣性導航系統之誤差方程式的狀態分別以卡門濾波器及H∞濾波器進行誤差估測,並進行比較。藉由各種不同雜訊干擾的輸入,以驗証H∞濾波器對不同雜訊干擾比卡門濾波器具有較佳的強建性。

      Strapdown Inertial Navigation System is an automatically operating guidance system, which has characteristics of high precision and high reliability in offering a complete information required in vehicle’s navigation regardless of weather conditions. It gives data showing vehicle’s headings ,velocities, and positions as well as the angles of vehicle’s pitch, roll and azimuth.

      In this research ,the kalman filter and H∞-filter are studied and used to simulate the error equations of the strapdown inertial navigation system respectively.A comparison between the above two filters is made for various noises and disturbances. The computer simulation results reveal that the H∞-filter is more robust in handling the various exogenous inputs other than the Gaussian white noise.
