摘　　要：空间稳定惯性导航系统的动基座初始对准过程中,由于其平台系统稳定在惯性空间的特点,传统对准网络存在对准时间较长,动态下对准精度不能保证的问题,本文考虑运用H∞控制技术设计对准方案,并进行了仿真设计。通过传统对准网络和H∞控制网络在对准性能和对准误差的比较,验证了H∞控制对于噪声的不敏感性,使系统在不确定干扰的噪声条件下的初始对准具有快速性和较高的精度,仿真分析表明H∞控制技术应用于空间稳定惯性导航系统的初始对准中,能有效缩短约初始对准时间。During dynamic alignment of space-stable inertial navigation system, because its platform system is stable in inertial space, the traditional alignment network has a long alignment time, and the alignment accuracy cannot be guaranteed under dynamic conditions. In this paper, H∞ control technology is used to design the alignment scheme, and the simulation design is carried out. Comparing the traditional alignment network and H∞ control network in alignment performance and alignment error, it is verified that H∞ control is insensitive to noise, which makes the initial alignment of the system fast and high accuracy under the condition of uncertain interference. Simulation analysis shows that H∞ control technology can effectively shorten the initial alignment of initial alignment time when applied in initial alignment of space-stable inertial navigation systems.
