Wind Shear Estimation by Frequency-Shaped Optimal Estimator

This paper presents a formulation of the frequency shaped optimal estimator and investigates the role of the measurement noise shaping function in this estimator. This shaping function creates transmission zeros and affects the singular values of the estimator transfer matrix, which can be used to improve control system robustness. The resulting estimator design technique has been applied to the estimation of wind shear on-board an airplane, and its performance has been simulated and compared with a reference Kalman filter.
