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。
Through the study of ship-to-ship combined guidance shift, the problem of consistency and convergence of control signals during shift is analyzed. After the analysis, the mathematical model of the tracking loop of composite seeker has been established and simplified And the mathematical model of its guidance and control system is constructed. Based on the mathematical model of the guidance and control system, the simulation analysis of the shift process under typical circumstances is carried out when the target of the ship-to-ship missile defense anti-ship missile is studied. The results show that: For this problem, based on the idea of adaptive handover law, when the shift is made, the shift operator is used to shift the shift or the missile distance is far and the tracking method is used as the guidance law when shift. The simulation results show that: Using the first-order function or the sine function as the shift operator and the long-distance shift, the tracing method can reduce the disturbance degree of the shift to the ballistic and improve the shift performance.
