Applications for helicopter control

It is necessary to investigate the design in landing-departure regimes of air vehicles for an aircraft carrier in a rough sea. Vertical, lateral and longitudinal movements of a helicopter have been analyzed and a new model has been established for the helicopter in simulation studies.Helicopter makes landing on and departure from an aircraft carrier which moves in three dimensions randomly. It is necessary for unknown disturbance factors to be rejected in a way to have the least effect in the system performance and to be able to track the reference input. A nonlinear adaptive controller has been designed for the above purposes. After examining Adaptive Internal Model (AIM) for linear systems, AIM applications were investigated for nonlinear systems and the robust controller has been developed for an helicopter. Performance of the controller has been verified by the simulations.
