| 摘 要： | 非理想状态下，无陀螺惯导系统存在模型误差和系统误差。通过研究系统的数学模型，分析了系统的模型误差；在一种九加速度计配置方案的研究基础上，采用线性化Kalman滤波，抑制系统误差的积累。仿真结果表明，线性化Kalman滤波对系统误差有较好的抑制作用。

| Abstract: | In imperfect condition, non - gyro inertial system has model error and system error. Model error of system is analyzed by investigating math model of system. On the basis of investigating distribution scheme of nine aeeelerometers, accumulation system error is controlled by linearization Kalman filter. The simulation result shows that linearization Kalman filter has good effect on controlling system error. |
