摘　　要：在研究捷联惯导系统的导航解算算法时,经常需要对算法进行仿真以测试算法的性能。比较研究了在Matlab中实现捷联惯导系统仿真的两种方法:一种是采用M语言编写各功能函数,通过函数调用的方式实现捷联惯导系统的仿真;另一种是采用Simulink模型与M语言结合的方式实现捷联惯导系统的仿真。分别用这两种方法进行了1h的导航解算仿真,仿真结果表明,这两种仿真方法均具有很高的仿真速度和仿真精度,都能满足工程应用的需要,与第一种方法相比第二种仿真方法可以方便地设定仿真时间、惯性测量组件的采样频率,也可以在仿真中暂停或停止仿真,具有更好的可操作性。It is necessary to test the performance of the navigation algorithm through simulation when researching SINS. The two methods with which SINS simulation is implemented using Matlab software have been studied. The first method implement SINS simulation through function calling,and the function is programed with M language. The second method use Simulink model with M language as the way to achieve the simulation of SINS. 1 h navigation simulation has been implemented with the two methods respectively. The simulation results show that the two simulation methods are of high simulation speed and simulation accuracy,and could meet the needs of engineering applications. But compared with the first method,the second one could be easily to set up the simulation time and the sampling frequency of inertial measurement unit. And you could also pause or stop the simulation when simulating. So the second method is of a better operability.
