In terms of the aircraft characteristics, the aircraft dynamics are divided into fast dynamics of Angle speeds and slow dynamics of roll Angle, Angle of attack and sideslip Angle.

根据飞机的动态特性，将飞机动态分为角速度快速动态与滚转角、迎角与侧滑角表示的慢动态。

For the aircraft with moderate swept wing, the main reasons of causing wing rock are the variations of roll damping moment with the Angle of attack and the sideslip Angle.

对具有中等后掠角机翼的飞机，产生机翼摇晃的主要原因是滚转阻尼力矩随迎角和侧滑角的变化。

This paper introduces two methods to get the virtual sensor signal of angle of attack and sideslip angle: Nonlinear Observer method and INS/GPS method.

本文介绍了两种方法来得到迎角和侧滑角的虚拟传感器信号：非线性观测器方法和利用INS／GPS系统数据估计迎角和侧滑角方法。
