The improvements in the iaga contained adding strengthen operator, improving evaluation index of premature, etc. multi - phase homing project, making use of the flight properties of parafoil system in gliding and turning, was simple in control and facile in practice. based on frenet frame, the linear time - variable error equations of parafoil system were built
基於frenet坐標系推導和建立了翼傘系統線性時不變的誤差方程，並運用「投影點」的思想來獲得frenet坐標系下偏差量的解析近似表達式，從而設計了用於翼傘系統航跡跟蹤的傳統pd控制器和增益調節型模糊pd控制器。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。In this algorithm, the difference between each tracking of different sensor are calculated, and as inputs are sent into the support vector machines to for judging the association between track and track. 3
把各個傳感器目標航跡狀態估計偏差作為支持向量機輸入，對各個傳感器的目標的狀態估計信息進行分類識別，從而實現多傳感器信息融合多目標跟蹤中的航跡關聯。
