通过对舰空导弹复合导引交班问题的研究,分析出交班过程中存在控制信号一致性和衔接性问题;经分析后,建立了复合导引头各子系统跟踪回路的数学模型且进行了简化,并构建出其制导控制系统的数学模型;以此制导控制系统数学模型为基础,进行了舰空导弹防御反舰导弹类目标时,典型情况下交班过程的仿真分析;结果表明:交班过程对弹道有一定扰动影响;针对此问题,以自适应交接律的思想为基础,交班时采用交班算子进行交班,或弹目距离较远且交班时采用追踪法为导引律;仿真结果表明:采用一次函数或正弦函数作为交班算子及远距离交班时,采用追踪法均可以降低交班对弹道的扰动程度,改善了交班性能.
通過對艦空導彈複閤導引交班問題的研究,分析齣交班過程中存在控製信號一緻性和銜接性問題;經分析後,建立瞭複閤導引頭各子繫統跟蹤迴路的數學模型且進行瞭簡化,併構建齣其製導控製繫統的數學模型;以此製導控製繫統數學模型為基礎,進行瞭艦空導彈防禦反艦導彈類目標時,典型情況下交班過程的倣真分析;結果錶明:交班過程對彈道有一定擾動影響;針對此問題,以自適應交接律的思想為基礎,交班時採用交班算子進行交班,或彈目距離較遠且交班時採用追蹤法為導引律;倣真結果錶明:採用一次函數或正絃函數作為交班算子及遠距離交班時,採用追蹤法均可以降低交班對彈道的擾動程度,改善瞭交班性能.

Consistency and connectivity existing in control signal in the handover process were analyzed based on the research of the handover problem of the composite guidance ship-to-air missile.The mathematical model of the subsystem tracking loop of composite seeker was built and simplified,and the mathematical model of guidance and control system was constructed.With these models,simulations of handover process in typical conditions were analyzed assuming the target such as an antiship missile was defended by ship-to-air missiles.Simulation results show that the handover process has certain disturbance on the trajectory.Regarding this problem,the handover operator was adopted based on the adaptive join law and the pursuit guidance method was used as the guidance law during the handover process and the missile-target distance was far away.Experimental results show that the disturbance ontrajectory is reduced and the handover performance was improved by using the linear or sine function as the handover operator,or using the pursuit guidance method when the missile-target distance was far away.
