AUTOLANDING CONTROLLER DESIGN USING ADAPTIVE CONTROL

This paper concerns with the adaptive based autolanding controller design by the means of MRAS (Model Reference Adaptive Systems) method. In that, Adaptive controller is used to design a controller which can land the aircraft smoothly on runway in severe conditions like gusts. A PID controller has also been designed to compare its performance with that of Adaptive controller. Two kinds of wind patterns, Strong and Very Strong in comparison to JFK Airport Downburst, have been induced to investigate the performance of the proposed controllers. Simulation results show that both controllers satisfy necessary conditions in presence of the strong wind but only Adaptive controller meets the necessary performance conditions, in presence of Very Strong wind. Therefore, this controller can expand the safety flight envelope of the aircraft.
