Pitch angular velocity estimate based on Kalman Filtering

直升机的姿态角速度不容易准确获得,本文提出了一种采用Kalman滤波理论对直升机俯仰角速度进行估计的方法,建立俯仰角速度方程,给出估计参数的Kalman滤波算法,实验证明该方法能够成功有效的估计直升机俯仰角速度。

It is difficult to get the attitude angular velocity of helicopter, this paper adopts Kalman filtering to estimate the pitch angular velocity of helicopter, establishes the pitch angular velocity equation and gives the parameter＇s Kalman filtering algorithm. Many experiments proved that this method can estimate the pitch angular velocity of helicopter efficiently.
