    Abstract: 本文研究以微機電飛行資訊量測系統為基礎之飛行姿態角之計算,探討以四元素法為核心之擴展式
    卡曼濾波器的設計,整合傳統四元素法及重力場計算飛行姿態角之運算法則,並以實際飛行數據執行
    實務驗證。此擴展式卡曼濾波器以傳統計算飛行姿態角之四元素法為動態模式,以四個元素為濾波器
    之狀態,重力場計算所得之飛行姿態角則視為系統之實際量測值。本研究首先利用四軸運動平台設計
    一個固定滾轉角飛行的實驗,由飛行資訊量測系統量測運動過程的三軸加速度及角速度,並分別由四
    元素法及重力場計算飛行姿態角,同時探討實驗誤差及量測雜訊之特性,之後再利用擴展式卡曼濾波
    器, 做互補濾波, 計算姿態角,驗證此卡曼濾波器設計的實用性。最後再以實際飛行數據來驗證本論
    文所提出的飛行姿態角之計算法則。
    This paper studies the attitude detennination using a MEMS flight infonnation measurement unit. A
    quatemion-based extended Kalman filter to integrate the traditional quaternion and gravitational methods for
    attitude detennination algorithm is proposed in the study. The proposed extended Kalman filter utilizes the
    evolution of the four elements in the quatemion method for attitude detennination as the dynamic model
    with the four elements as the states of the filter. The attitude obtained from the gravity computation is treated
    as the measurement of the filter. An experiment using an in-house designed motion platfonn is designed to
    evaluate the proposed algorithm. From the experiment, the noise characteristics of the sensor signals are
    examined. The proposed filter design is then validated using the laboratory data. With the success in the
    laboratory test, a set of flight test data is utilized to show the practicality of the filter design.
