摘要
针对常用惯导仿真方法对模拟长时间复杂条件下工作的巡航导弹惯导系统存在一定难度的问题,在分析平台惯导系统数学模型的基础上,通过设计巡航导弹典型飞行航迹,建立惯导器件误差仿真模型,对含有误差的惯导系统进行导航解算,构建了完整的巡航导弹惯导系统仿真模型。利用MATLAB/Simulink工具对模型进行了仿真与误差统计分析。得到的导航位置误差和速度误差与实际情况基本相符,证明仿真模型建立正确,方法使用得当。为进行惯导及组合导航研究提供了一种实用方法。
To solve the problem that common simulation methods can't effectively simulate the cruise missile Inertial Navigation System (INS) under complex condition, a complete simulator of cruise missile's INS based on the mathematical model is established in this paper. The designs of cruise missile special track, simulating model of IMU errors and navigation are also included. The simulation using MATLAB/Simulink is analyzed. And the scheme is proved to be efficient for simulating the INS.
