This paper was designed from the point of view of control to study sins initial alignment , hammer at to get a better strapdown system initial alignment method 本论文主要是从控制角度出发来研究捷联惯导系统的初始对准问题,力求获得高精度,高可靠性的初始对准方法。
Through the correlative theoretic analysis and simulation , this algorithm can be used to finish the initial alignment of the low cost inertial measurement unit 理论分析和仿真计算表明,这种算法仅受组合系统自身硬件条件的约束,可以较好地应用于组合系统中低成本惯性单元的初始对准。
More important , a new method of initial alignment was developed for the strapdown navigation system ( sins ) by designing a dynamic controller using h _ ( 2 ) and h _ ( ) optimize control theorems 更为可贵的是,本文把现代控制理论进入到初始对准过程中,应用h _ 2和h _优化控制理论设计的动态控制器来进行初始对准。
Initial alignment is one of the key ins ( inertial navigation system ) technologies . the capability of the sins ( strapdown inertial navigation system ) is relate to the speed and precision of initial alignment 初始对准技术是惯性导航系统的关键技术之一,初始对准的快速性和精度直接关系到捷联惯导系统的性能。
The conclusion was drawn that the chosen initial alignment algorithm and attitude updating algorithm can meet the requirement of torpedo sins , and it is shown that the designed torpedo project is feasible 得出了所选用的初始对准和捷联矩阵更新算法完全满足系统要求的结论,说明为某型鱼雷捷联惯性系统设计的方案是可行的。
