They are also designed to have optimal performance in the case of a hard landing. In general, the tasks of aircraft landing gears are complex and sometimes lead to a number of contradictory requirements. Although there are existing modi cations of aircraft shock absorbers to reduce the problem, the basic design con ict between the requirements for landing and for rolling cannot be fully overcome by a passive suspension layout. Active and semiactive suspension techniques are a solution to this problem and are capable of reducing fuselage vibrations e ectively. In order to get satisfactory damping performance with active and semiactive devices, appropriate control laws must be employed. In this paper, we study the use of an adaptive backstepping control with H-infinity performance to cope with disturbances, uncertainties and nonlinearities, typical of suspension systems and damping devices. A comparison between active and semiactive strategies is provided through the analysis of simulation results Preprint Àrees temàtiques de la UPC::Enginyeria mecànica::Mecànica::Vibracions mecàniques Àrees temàtiques de la UPC::Matemàtiques i estadística Vibration (Aeronautics) Damping (Mechanics) Vibració (Aeronàutica) Amortiment (Mecànica) Classificació AMS::93 Systems Theory; Control Landing gear suspension control through adaptive backstepping techniques with H-infinity performance
