| 摘 要： | 提出并设计了把状态空间解耦原理应用于平台惯导系统的一种快速初始对准方法。通过配置控制器将三个平台失调角进行解耦使其跟踪三个方向上的陀螺漂移 ,采用内外两层卡尔曼滤波器进行状态估计。仿真结果表明 ,该方法收敛较快、对漂移的抑制效果较好、对准精度高、简单易行。

| Abstract: | In this paper an initial alignment method in which the state decoupling principle of linear system is used in platform inertial navigation system is presented. In this method, the three error angles are decoupled by designed controller so as to track the gyro drifts in three directions respectively, also the system states are obtained through two Kalman filters. Finally the simulation result shows this method is more quick, simple and practicable. |
