基于LQ优化的航空交通管理

随着航空交通流量的增长,通过对交通流进行的改进,后与元胞理论结合,改进了一维元胞传输。接着,再应用线性二次型(Linear-Quadratic)最优控制的理论对空中流量模型进行分析,实现对某区域的流量进行预测。最后,利用Matlab对系统进行了仿真。模型在仿真过程中考虑了扰动输入,流量更新的随机性,对不同的流动比例系数下,获得的控制序列与反馈增益进行了比较。结果显示某个空域范围的交通流量得到了改善。

With the increase of air traffic flow, the one-dimensional cellular transmission is improved by improving the trafficflow and combining with the cellular theory. Then, the Linear-Quadratic optimal control theory is applied to analyze the air flowmodel to predict the flow ina certain area. Finally, the system is simulated by Matlab. In the process of simulation, the randomnessof disturbance input and flow update are considered, and the control sequence and feedback gain are compared under different flowratio coefficients. The results show that the traffic flow in a certain airspace is improved.
