摘要 研究了摇摆状态下捷联惯导系统罗经法自对准技术,设计了水平、方位精对准参数以及基于MATLAB/SIMULINK的参数分析系统,最后进行了基于VC++6.0的捷联惯导系统罗经法自对准的软件设计、仿真分析与精度评估。仿真结果表明,罗经法自对准在不同海情、不同初始姿态误差角、全方位、带量化误差的条件下均具有较高的对准精度、较好的快速性和动态品质,能够满足捷联惯导系统在摇摆基座下实现自对准的要求,同时为下一步的工程应用提供了依据。 The gyrocompass self-alignment of strapdown inertial navigation systems(SINS) on swing base was discussed, and the free alignment parameters of level and azimuth and the parameter analysis system based on MATLAB / SIMULINK were designed. The software design, simulation analysis and the precision evaluation of the strapdown gyrocompass self-alignment, based on VC++6.0 platform, were presented, The simulation results show that the gyrocompass self-alignment of SINS, under various marine conditions, various errors of initial angle, all-directional angle or with quantification error, can all meet the requirement of SINS initial alignment with high accuracy, quick reaction and high dynamic quality on swing base, The research provides a basis for the further application.
