阻尼技术用于抑制惯性导航系统的周期性误差.传统的阻尼网络参数一般采用试错法确定.针对传统阻尼的方法的若干局限性,如固定的阻尼比、繁琐的网络参数确定过程等,提出了改进的阻尼技术.水平阻尼和方位阻尼网络,均分别由一个与阻尼比呈正比的参数控制,具有一般意义上的通用形式,可以方便地调整所需的参数大小.与传统的阻尼,改进的阻尼方法简化了阻尼网络设计过程,能够抑制超调过渡过程以及减少载体运动的敏感性.仿真结果和实测数据均验证了上述优势.

Damping technology is often used to suppress periodic errors in inertial navigation system(INS). The parameters of conventional damping equalizers are determined by trial and error. To overcome the limitations of conventional damping methods, such as unchangeable damping ratio, fastidious determination of equalizer parameters, an improved damping method using adjustable damping equalizers is proposed in this paper. Both level damping and azimuth damping equalizers have only a single parameter which is proportional to damping ratio. The improved equalizers have general forms and can conveniently adjust the single parameter to obtain required damping equalizers. Compared with conventional damping equalizers, the improved damping method can avoid trial-and-error procedure in determining damping ratio and other parameters, simplify the design of damping equalizers, suppress switching overshoots, and reduce the sensitivity to vehicle motion. Simulation results and measured data have both verified the above-mentioned advantages.
