摘要
介绍了仿真软件MATLAB/Simulink及先进的仿真系统平台软件RT-Lab,设计了龙格-库塔积分模块,用于解决在使用定步长求解器及数字时钟情况下的积分精度不高的问题;建立了基于MATLAB/Simulink的捷联惯性导航仿真模型;并将系统分解成一系列功能相对独立的模块,如轨迹发生模块,捷联惯导解算模块;并进行了仿真验证,得到的姿态、速度、位置误差与理论值相符,证明了仿真模型建立正确、方法采用得当、有效。
The advanced simulation system platform RT--LAB and software MATLAB/Simulink are expounded, the Runge--Kutta integrator models is designed , and strap--down inertial navigation simulation models based on MATLAB/Simulink is built. The system was divided into a series of independent functional units, such as track generation unit, strap--down inertial navigation unit. And take the validate, Comparing with the real data, the results show that the model is sound and the method is validity.
