Abstract

 This paper is devoted to the robust flight control law design for lateral channel of small Unmanned Aerial Vehicle (UAV) based on H2/H∞-robust optimization technique. The task is divided into two stages. On the first stage a linear quadratic regulator is synthesized based on Luenberger observer. The second stage is devoted to the robust optimization procedure of the constructed regulator. The robust optimization technique applies genetic algorithms. It is known that the genetic algorithm optimization is more robust than traditional optimization procedures, also it has the propriety to converge to the global minimum and well suited to seek a compromise between contradictory requirement expressed in terms of multi-objectives function. The simulation results prove the efficiency of the proposed procedure

Keywords
