Abstract
AbstractIn this contribution we investigate the problem of linear velocity estimation of a Gun Launched Micro Air Vehicle (GLMAV), which is a new Micro Air Vehicle (MAV) concept, intended for outdoor flight, and using two-bladed coaxial contra-rotating rotors. The linear velocity estimation is realized using a simple time-varying Luenberger-like observer, and only using partial measurmements of an Inertial Management Unit (IMU). Simple conditions of the observation-error-asymptotic-stability are given in terms of physical variables of the GLMAV. The reduced-order observer stability analysis is realized through the Lyapunov approach and the Barbalat's lemma. Simulations results show the effectiveness of the estimation technique applied to the presented GLMAV model, identified from experimental results.
