Research On Formation Optimal Design And Optimal Control For Integrative Penetration And Attack Of Missile Formation Cooperation

The penetration of single missile is becoming more and more difficult with the further development of the integrated defense system in five-dimension battlefield of land, sea, air, sky, electricity, leading penetration capability to be one core technical indicator which measures the quality of missile operational effectiveness, as well as drawing great attention of the weapon and equipment development organizations. The developing level of cooperative operations of missile formation, which is considered one effective means to improve missile penetration ability in information warfare and do damage to large objects for its good robustness and concealment, restricts the development of next generation missile directly. Thus it becomes an urgent problem that how to improve the formation cooperative engagement capability under the condition of informatization.This article proposed a new integrated conception of missile formation cooperative penetration-attack, aiming to improve the missile cooperative penetration ability and targets strike capability in the process of formation cooperative engagement under the precondition of minimal energy consumption.Under the background of the integrative operation of missile formation cooperation, the method of formation design which is suitable for formation integrative combat, the accuracy fused estimation algorithm for the formation estimating battlefield situation, and the compound control method which can improve the inherent mobility of the formation are studied firstly. Then on the basis of the above-mentioned study, an in-depth study of the optimal control problem of integrative penetration and attack for missile formation cooperation is completed, which provides theoretical basis for the ascension of formation cooperative operational effectiveness and its engineering implementation.The main work and research results of the paper are as follows:Firstly, missile formation, which has been designed considering both coordinated penetration capability and attack capability, provided parameters of formation for coordinated detection and coordinated penetration-attack in the future work. In the consideration of the limitation of the inherent properties of missile and mathematical characterization method, the author analyzed the influence of formation parameters on coordinated penetration-attack with the use of analytic hierarchy process, triangle fuzzy number and engineering experience. To improve the speed of formation optimization, fuzzy evaluation method was used to decrease the number of optimal variables and shrink the value range of the variables. The author also design a kind of missile formation which suits the condition of coordinated penetration-attack based on the improved genetic algorithm. The designed formation can meet the demands for communication and flying, keep good tracking accuracy in the process of coordinated detection, keep sufficient mobility space in the process of coordinated penetration and do greater damage to the targets when coordinated attacks were implemented.The study on the tracking and estimation of the interceptor missile and target after coordinated penetration and attack has been discussed to improving the perception to the battlefield. Firstly the quick data association of the multiple detection targets, in the condition of multiple interceptor missiles and attack targets, was completed through changing the association order based on the clustering thought, which provides the motion state estimation of the interceptor missile or target with prerequisite. After the association completed, estimating the motion state of the interceptor missile or target with improved particle filter method and weighted fusion algorithm, thus providing more accurate estimation and prediction of the targets.To improve the inherent motor performance, the control model of every single formation member was established considering the influence of the direct force, which provides a theoretical basis for postulating the response parameters of formation members. The model of attitude control motors is built firstly, and then the autopilot of compound controller is designed based on decomposition of control instruction. The controller response to guidance command in a quicker way compared to pneumatic controller.The paper investigated the initiative anti-interception maneuver penetration(IAIMP) of formation member based on the optimal control theory to ensure the attack ability after penetration. In the precise of accurate motion state estimation for interceptor missiles and targets, cooperative penetration strategy, which helps develop optimal control model of IAIMP, was put forward based on combat geometric advantage. Based on control variable parameterization method and the path constraint discretization method, the numerical solution of guidance command sunder the given penetration occasion can be gotten. Then an innovative Hybrid Genetic Algorithms based on control variables parameterization, named CVP-GA, is proposed to obtain the optimal penetration occasion and guide commands.Optimal control of coordinated penetration-attack was discussed to keep the integrated damage effect on the time/angle of the targets after coordinated penetration. The task decomposition and constraint models of formation cooperative operation were completed on the basis of coordinated penetration-attack strategies and modular modeling ideology. And the adaptability to different strategies was achieved by developing continuity constraint model. Based on above-mentioned study, the formation multi-stage optimal control model was developed and numerical solution of the guide commands was solved according to improved Multi-Stage Pseudo Spectral Method, leading time-optimal control of the formation coordinated penetration-attack achieved.
