惯导系统初始对准网络参数优化设计软件的实现

The realization of the network parameter design of INS initial alignment

初始对准技术是惯性导航系统的关键系统技术之一,而系泊状态下船用惯导系统由于受到外部干扰会导致初始对准精度降低.该文以设计具有抗干扰能力的初始对准网络参数为目标,分析了惯导对准回路网络参数的设计方法,进而开发了能自动完成初始对准网络参数设计及验证的系统软件,并通过实例设计对系统软件进行了分析验证.仿真结果表明,该软件能根据对准参数的设计要求,能自动完成对准网络参数的设计及验证.

Initial alignment is one of the key technologies of navigation systems, but in moorage, the external interference will cause the loss of accuracy in the initial alignment of naval navigation systems. The purpose of this paper is to design a network parameter of initial alignment which has the capacity of resisting disturbance, analyse the design method of the alignment loop network parameter, and develop a software to design and verify the network parameter of initial alignment automatically. Also the software can be verified by the instance. The simulation results indicate that the software can design and verify the network parameter automatically according to the requirement of the parameter.
