  1. Traditional inertial mechanized - platform uses velocities to damp the system attitude to improve the precision of attitude, when the system acceleration is small. referring to the idea, this paper designeda damp kalman filter in strap - down attitude heading reference system ( ahrs ). the new method makes use of 3 - d accelerometer ' s measurements to estimate the system attitude, which is measured to compensate attitude errors. because the acceleration affected the precision of fiher directly, the fuzzy adaptive system was presented. the fuzzy logic inputs are three accelerations and the output is to control the measurement noise covariance matrix. simulations and experimental results prove that the damp algorithm can damp most of schuler oscillation and foucauh oscillation, so that to assure the filter convergence and efficiently improve the precision of strap - down ahrs

    在系統機性不強的情況下,傳統的平臺內阻尼演算法將系統本身的速度信息通過阻尼網路加到系統中,達到提高姿態角精度的目的.將這種平臺內阻尼的思想引入到捷聯慣性航姿系統中,在系統加速度較小的情況下,利用加速度計的輸出估計系統姿態角,通過卡爾曼濾波的補償系統姿態誤差.於加速度的大小直接影響濾波器精度,本文設計了模糊適應卡爾曼濾波演算法,根據三軸加速度計的輸出調整內阻尼量測誤差方差陣,從而避免了濾波器的發散.模擬和實驗驗證,內阻尼演算法可明顯抑制舒勒周期蕩和傅科周期蕩,避免了系統姿態漂移,有效提高了捷聯慣性航姿系統的精度
  2. In the recent years, with the development of microcomputer technology and the needs of industrial automation. we use computer to realize the control algorithm. but during the time of realizing the vsc, because of the limits of sampling, the ideal sliding mode does not exist

    近年來,隨著計算機技術的飛速發展和工業化領域的實際需要,控制演算法的實現經常利用數字計算機,但當採用數字計算機實現變結構控制演算法時,於采樣過程的限制,理想的滑模態不存在,狀態軌跡以抖沿著滑平面運,這是不利於工程的實際應用的。
