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 techniques are used to suppress periodic errors in inertial navigation systems. Traditional damping network parameters are usually determined by trial and error. Aiming at some limitations of traditional damping methods, such as fixed damping ratio, tedious process of determining network parameters and so on, an improved damping technology is proposed. The horizontal and azimuthal damping networks, each controlled by a parameter proportional to the damping ratio, have a general form in the general sense that allows easy adjustment of the required parameter size. With traditional damping, the improved damping method simplifies the damping network design process and can suppress overshoot transitions and reduce the sensitivity of the carrier motion. The simulation results and the measured data verify the above advantages.
