UAV state Kalman filter estimation in turbulent flow
Wei Hong-shen · Flight Dynamics · 2012
For decreasing the influence of the turbulent flow on the flight speed and simulating the state response of the UAV in the presence of turbulent flow,this paper puts forward the colored noise model of the turbulent flow based on the numerical method which accords with the reality.Then a colored noise Kalman filter for the flight speed of UAV is presented,which can extend the application fields of the Kalman filter,by whitening the system noise.The simulation results demonstrate that this filter can decrease the influence of the turbulent flow and improve the estimation accuracy of the flight speed.
