Research On Multi-Missile Cooperative Engagement Technology

As the accelerated integration of the high-tech triphibious warfare and information warfare,it would be the rivalry between systems in the future war.In this case,a single missile could not give full play to the effectiveness in combat as the main weapon.The penetration ability,electronic countermeasures ability,collaborative search ability and integrative battle effectiveness would be improved significantly in the case of multimissiles in co-ordination.The technology of control of the multi-missiles formation and saturation attack would be the key technologies for the multi-missiles cooperative engagement.Establishes the motion equations of the leader and the followers in the ballistic coordinates of the leader and designs the ideal flight paths of the leader and the followers in consideration of the time of formation and saving energy for the leaderfollowers mode of formation based on the Gauss pseudo-spectral method.Designs a trajectory tracking of followers to achieve and hold the formation by controlling the followers to track the ideal trajectory in the presence of interference assumed that the leader could follow the optimized trajectory with the acceleration of the followers as the variables based on the dynamic surface control theory and the extended state observer.Assumes that it would be the distributed communication mode between the leader and the followers and the followers could get the information of position and velocity of the leader and the information of position of the adjacent followers which have the communication with it.Sets the communication topology between the leader and the followers and designs the command of the velocity,the trajectory inclination angle and the trajectory deflection angle of the followers to make multiple missiles form the specified formation based on the consensus algorithm in the case of the motion of the leader had been confirmed.Designs a robust controller to follow the command of the velocity,the trajectory inclination angle and trajectory deflection angle of the followers based on the dynamic surface control technique and the extended state observer then proves the stability of controller by Lyapunov theory.To achieve the corporation by the lateral maneuvers under the assumption of the missiles fight with a fixed attack angle in consideration of multiple bank-to-turn missiles saturation attack the target.Regards the average value of the missile-target distance of the missiles as the ideal missile-target distance and the missiles make the actual missile-target distance track the ideal one by adjusting the lateral velocity heading angle and the gets the ideal command of velocity heading angle of each missile by a controller based on the dynamic inversion theory.Establishes the dynamical model of the bank-to-turn missile with nonlinear unknown uncertainties in view of the model errors and the extended interference.Estimates the nonlinear uncertainties by the fuzzy adaptive technology and designs the tracker to make the velocity heading angle of the followers track the ideal ones to achieve the saturation coordination attack based on the dynamical surface control theory.
