  1. The problem is then fed to a nonlinear programming routine to solve for all parameters. the flight dynamics model with yawing motion of uh - 60a is given, scale factors of state variables and control variables are applied based on the consideration of algorithm convergence. then, the optimization of trajectories is expressed as optimal control problem with a performance index constrained by helicopter performance limits, faa regulation and so on

    首先,建立帶偏運動直升機點質量模型,然後對狀態變量和控制變量進行無量綱處理,因為狀態變量和控制變量量值相差較大,這使得優化演算法收斂效果變差,所以需要擇適當縮放因子,最後把直升機單臺發動機停車后飛行軌表示成一個最優控制問題,即在考慮直升機性能限制和far規范后,指一個優化性能指標,擇合適路徑約束,然後再解最優控制問題。
  2. The same target will appear two courses on the electronic chart for the errors of the two sensors are statistically independent. the paper mainly includes two points : ( 1 ) study the fusion between ais data and radar data in vts ; first the paper discusses the kalman filter of the target ' s tracking. on the basis of which we study the data fusion between the track of radar target and that of ais target

    對于雷達目標擇雷達作為位置傳感器,對于ais目標,擇gps (全球位系統)接收機作為位置傳感器,由於測量雷達和ais傳感器是不同,兩種傳感器誤差是相互獨立,這樣在海圖上顯示目標時候出現對于同一目標出現不同,本研究重點包括兩個方面: ( 1 )研究vts系統中ais數據和雷達數據融合:首先討論目標kalman濾波,在目標kalman濾波基礎上對雷達目標和ais目標進行數據融合研究;同時本研究將對ais位置傳感器分差分gps和非差分gps兩種情況進行分析和處理。
