An algorithm of online wind field estimation for small fixed-wing UAVs

Roll angle and sideslip angle were usually ignored in the traditional wind field estimation for small fixed-wing UAVs. Aimed at solving this problem, a new algorithm is proposed in this paper. Firstly, the model with roll angle and sideslip angle considered is established and the error curves of roll angle and sideslip angle are obtained. Secondly, the estimated values of roll angle and sideslip angle are got from Kalman filter. Finally, simulation based on multi-step estimation is carried out to verify the designed algorithm. Simulations show that the proposed algorithm achieves good performance.
