最坏风模型及对飞机突防航迹跟踪的影响

WORST-CASE WIND MODELING AND ITS INFLUENCE ON CAPTURING OF AIRCRAFT PENETRATION TRAJECTORY

针对一类非线性动力学系统,本文推导出二次型性能指标下的微分对策解,由此得到一组含有非线性因素的最环风模型,这一模型特别适用于研究作空间机动飞行的飞机受外界环境扰动的灵敏性问题。最后考察了这一变化风场对飞机突防航迹非线性解耦跟踪的影响。

Based on a kind of non-linear dynamic equations,the differecntial game solutions of quadratic payoff function are developed,so the worst-case wind models contatining non-inear factors are constructed.This model especially pertains to analyse disturbance sensitivity problem of aircraft during spatial maneurering flight.Finally,how the non-linear decoupling ccapturing of aircraft penetration trajectory is affected by this variable wind field is discussed.
