【摘要】 基于全自动着舰闭环仿真模型,分析了传感器信号误差对着舰的影响.根据全自动着舰系统的组成和作用,建立了完整的机、舰、环境闭环仿真模型.根据传感器信号误差的主要影响因素以及本文的研究需求,建立了参数化的机载传感器模型.在建立的全自动着舰闭环仿真模型基础上,通过仿真试验的方法,分析了各类机载传感器和滤波器环节对全自动着舰控制的影响.研究结果表明,传感器测量误差会使舰载机下滑着舰过程中的高度和侧向航迹偏差增大,若无滤波器环节,着舰精度将会明显下降.更多还原

【Abstract】 On the base of the closed-loop automatic carrier landing simulation model,effect of sensor signal error on automatic carrier landing control is analyzed.This paper sets up a complete automatic carrier landing system according to its components and functions including carrier-based aircraft,aircraft carrier and carrier landing environment,and a parameterized model of airborne sensors is built by considering main influencing factors of sensor’s data precision and research needs,which can be used to analyze the effect of airborne sensors and filters on automatic carrier landing control,through the simulation tests,based on closed-loop automatic carrier landing simulation model.The result shows that measure error of airborne sensors will increase height deviation and Lateral flight path deviation in the process of carrier-based aircraft approach glide-down and landing,and automatic carrier landing accuracy will decrease obviously without filters.更多还原
