Wind Estimation Based on Estimation of Lateral-Directional Stability Derivatives of Aircraft

抄録

This paper considers estimating wind using only the data of an inertial measurement unit without using any information from an air-data sensor and model parameters by estimating stability derivatives of a lateral-directional motion model of an aircraft. Assuming that the wind is constant, the relation between wind and stability derivatives, which allows the wind to be calculated, can be derived. An advantage of this method is that the estimated wind is relatively insensitive to the estimation error of the derivatives. The authors illustrate the effectiveness of the proposed method by simulation using NASA’s Generic Transport Model.
