A Design of Airplane's Integrated Ground Directional System with Fuzzy Control

Considering characteristics of aircrafts body, tyre, ground conditions and nose wheel steering system, the nonlinear dynamic model of the integrated ground directional control system which contains the rudder control system, the aircraft antiskid braking control system and the nose wheel steering control system is given, and a interpolation online fuzzy control is adopted in the nose wheel steering control system. It is confirmed by simulation that this new designed fuzzy controller can eliminate steady-state error and avoid the oscillation effectively when the main gears are in the different ground conditions respectively.
