Research On Time-space Synergy Method And Simulation Of Multi-missile

With the development of tank technology,the new armor and active defense technology of tank have improved the current tank’s defense capability.However,with the arrival of "Swarm"technology,it is necessary to introduce "Swarm" technology into the field of anti-tank missile,that is,multi-missile cooperative attack technology.In the technology of multi-projectile cooperative attack,it is mainly embodied in the time synergy and space synergy.At present,the domestic and foreign research results on time synergy are very rich,but the research on space synergy is still relatively few.Therefore,the combination of time synergy and space synergy research has a very important research value.Relying on the line of sight(LOS)between the missile and the target expected by multiple missiles,this dissertation starts from their relative direction to strike the target and finally achieve the hit.This dissertation proposes a multi-missile time-space synergy method which combines time synergy and space synergy to guide multiple missiles.Firstly,by analyzing the relative motion relationship between multiple missiles and a target,the time-space synergy mathematical model of multiple missiles is established.Then,based on the multi-agent cooperative control theory,the multi-missile time-space synergy method is designed from two directions:(1)the distributed time synergy method is designed from the line of sight direction;(2)the distributed spatial synergy method is designed from the line of sight in vertical direction.The design from the first direction is to ensure that impact time of all missiles can be consistent in finite time.The design from the second direction is to ensure that the relative LOS of all missiles can converge to an expected value in finite time.Finally,the effectiveness of the method is verified by Matlab/Simulink simulation.It is proved that the method can make the missile group hit the enemy target simultaneously from the expected missile target relative line of sight direction.The simulation results show that all missiles can hit the target in a limited time,which meets the expected effect of the dissertation.This method can not only make the relative distance,relative distance rate and remaining flight time tend to a fixed value in about 14s under the action of overload command in line of sight direction;Moreover,the relative LOS angle error and LOS angle rate converge rapidly under the action of overload command in line of vertical sight direction,and finally approach zero in about 12 seconds.At the same time,the available overload of each missile in line of sight direction and vertical sight direction is smaller than expected.The simulation results show that the miss distance of the missile group is less than 1.390m;Their relative Los error tends to zero faster and less than 4 × 10-6(°);The maximum time deviation is less than 0.1s.Therefore,the multi-missile time-space synergy method described in this dissertation has certain advantages and effectiveness in missile guidance,and also improves the missile combat capability.
