Abstract:
|
Landing gear suspension systems ful ll the tasks of absorbing the vertical energy of the
touch-down as well as providing passenger and crew comfort with a smooth ground ride before
take-o and after landing. 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 |
