摘要:
本文分析了捷联惯性导航系统(SINS)进行初始对准的基本原理,简要介绍了遗传算法的搜索过程,并将其用于SINS的初始对准之中.根据初始对准的本质构建了GA的适应度函数,确定了遗传算子,基于惯性器件的量测值对这一过程进行了计算机仿真.仿真结果表明,将GA用于SINS的初始对准,精度与常规方法相仿,但由于GA的并行性和简单性,使得对准时间大大减少,具有很大的优越性.
Abstract:
This paper analyses the basic principle of the initial alignment of the strap-down inertial navigation system (SINS), briefly introduced the searching progress of the GA and then utilized this method to the initial alignment of the SINS. According to the essence of the alignment, the fitness function was built up and the operators of the GA was determined. Based on the measurement of the inertial measurement units, the computer simulation was done as well. The simulation shows that the alignment precision of the GA method is almost the same as the normal methods, however, because of the parallel and simplicity of the GA, the alignment time is greatly reduced. So this method is of great advantage.
