摘要
针对捷联惯导系统的实际应用需求,在Matlab/Simulink环境下设计并实现一种面向捷联惯导系统设计/验证的仿真平台。该平台主要由轨迹发生器、惯性测量单元模块、捷联解算模块、卡尔曼滤波器模块、导航性能评估模块等组成,在其上可方便的完成捷联惯导系统算法的设计验证、系统误差分析、惯性元器件误差分配及试飞数据的离线分析等功能。研究结果证明了该仿真平台的有效性和实用价值。
According to practical application requirement of strap-down inertial navigation system(SINS),a simulation platform for design and validation of strap-down inertial navigation system based on Matlab/Simulink was designed and realized.The platform includes flight trajectory generator,inertial measurement unit(IMU),SINS unit,Kalman filter unit and navigation performance evaluation unit.It has functions of SINS algorithm validation,error analysis,error distribution and flight data off-line analysis and so on.The research results prove the simulation platform is effective and practical.
