Then the pose of longitudinal motion is estimated by linear Kalman filter. Finally, an optimal control rule is constructed by LQG performance index.
其次，利用线性卡尔曼滤波器对其纵向运动姿态进行估计，依据LQG性能指标构造了最优控制规律。

Finally, the longitudinal expansion thought of high-order cascade filter design was presented.
最后，本文提出了高阶级联滤波器的纵向扩展设计思路。

The attitude feedback processed by a filter was used to adjust continuously the parameters of the reference point, and the lean along the longitudinal and lateral direction are compensated.
