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,建立帶偏航運動的直升機點質量模型,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,所以需要選擇適當的縮放因子,最後把直升機單臺發動機停車后的飛行軌跡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,指定一個優化性能指標,選擇合適的路徑約束,然後再解最優控制問題。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
對于雷達目標的航跡,選擇雷達作為位置傳感器,對于ais目標,選擇gps (全球定位系統)接收機作為位置傳感器,由於測量雷達航跡和ais航跡的傳感器是不同的,兩種傳感器誤差是相互獨立的,這樣在海圖上顯示目標的時候出現對于同一目標出現不同的航跡,本研究的重點包括兩個方面: ( 1 )研究vts系統中ais數據和雷達數據的融合:首先討論目標航跡的kalman濾波,在目標航跡kalman濾波的基礎上對雷達目標和ais目標的航跡進行數據融合的研究;同時本研究將對ais的位置傳感器分差分gps和非差分gps兩種情況進行分析和處理。
