摘要
根据惯导平台转动的工作特性,采用卡尔曼滤波的方法,可实现对速率偏频系统误差参数的估计。在静基座条件下,该误差标定通过建立新系统误差方程和滤波方程的及标定过程的仿真两步实现系统的各误差项的标定。仿真表明,估计效果能满足误差标定要求。
Based on the rotation characteristic of rate offset frequency platform, applying Kalman filter method, the error parameters of rate offset frequency were realized. Under the static base condition, through establishing error equations of new system, constructing filter equations and stimulating calibration equations, the calibrations of each error items were realized. The stimulation proved that the evaluation results could meet the needs of error calibration.
