Abstract :
A robust asymptotic output command tracking controller is proposed to control the longitudinal motion of an aircraft model involving atmospheric gusts. The controller covers various flight conditions. The stability derivatives of the aircraft and the velocity of the aircraft are considered to be uncertain parameters. The output of the closed loop system tracks step and ramp type reference signals. The derivation of the controller parameters is based on a robust stabilizability algorithm appropriately enriched by a metaheuristic search algorithm.
