Research On Numerical Optimal Method Of Pursuit-evasion Among Multiple Aircrafts

As technology development,modern wars have appeared local high technical features,and they have tended to fight and win dominance in information technology and air supremacy.Therefore,the aircrafts play a more and more important role in wars.Their combat forms prefer to small scale formation operation and hybrid formation operation.And the cooperative air combat mode which can fully play formation performance catches more and more attention.The main works of this thesis are as follows:(1)The movement,guide and control model of theaircraft are introduced.Firstly,the necessary coordinate systems are introduced.Secondly,the forces and moments on the aircraft are analyzed.At last,the dynamic and kinematic equations of the aircraft are constructed.(2)The theoretical model of optimal control of multi-aircraft cooperative pursuit-evasion is introduced,which includes the minimum principle and some promotion forms.Specially,the numerical solution of optimal controland its application on multi-aircraft fight problem are presented in detail.The scheme and the algorithm of multi-aircraft cooperative pursuit-evasion based on the minimum principle are proposed,which includes the reasonable detecting model of the airborne sensors and the objective function and the solution of multi-aircraft cooperative pursuit-evasion.(3)On the basis of the proposed algorithm model and the mathematical model of the aircraft,the simulation verification platform of multi-aircraft cooperative pursuit-evasion is constructed.Then the simulationof the proposed algorithm is carried out.The simulation results show that the proposed algorithm of the multi-aircraft cooperative pursuit-evasion is feasible and valid.
