摘要
舰载武器传递对准由于受海浪冲击、舰船自身载荷等因素影响,导致主、子惯导之间存在模型未知的挠曲变形,影响传递对准精度。针对上述问题,论文提出了模型预测滤波技术,应用于传递对准中,可以有效对挠曲变形进行预测估计,补偿传递对准误差。通过数值仿真分析,验证了该算法的有效性和可行性,能够提高传递对准精度。
When shipborne weapons are impacted by waves,loads and other factors,there is an unknown deflection deforma⁃tion,so that which affects initial alignment accuracy.In the view of problems above,model prediction filter technology is proposed in this paper,and the algorithm is applied in initial alignment,which can estimate deformation to compensate alignment errors.Ac⁃cording to simulation analysis,the feasibility and effectiveness of model prediction filter technology is tested,which can improve alignment accuracy.
