摘要
针对空中交通流量需求的日益增长,通过对交通流LWR理论进行改进与元胞模型理论相结合,建立改进的一维元胞传输模型。采用离散控制系统线性二次型最优控制理论对模型进行了分析研究,实现对特定区域内流量进行预测。利用Matlab对系统进行了仿真,对不同流动比例系数下得到的控制序列和反馈增益进行比较,通过采样数据的比较,得出的结果显示,空域单元的飞行流量得到改善。
According to the increasing demand of air traffic flow, a modified 1-D cell transmission model was introduces by combining modified traffic flow LWR theory and cell model theory. Linear-quadratic optimal control technique of discrete control system was applied to analyzing and investigating the model. The flow prediction in special area was realized. The model was simulated by Matlab. The control sequences of different flow proportionality factor with feedback gain were compared. Through comparing sample data, the result reveals that air traffic flow in the airspace unit has been improved.
