A fuzzy control method with the optimized intelligent weight function for directional control during aircraft autoland rollout

Abstract Aircraft landing rollout process is a complex and high non-linearity process. The mutual effects of tire dynamics, aerodynamics multi-body dynamics should be taken into considerations. It difficult to accurately expressed in mathematics. Aiming at obtaining good directional control capability during aircraft autoland rollout, comprehensive simulation system was constructed including all those three aspects above, fuzzy method with intelligent weight function adopted which appropriate for systems modeled exactly. In the paper’s work, optimized by power first time. By adjusting exponential k , rules can conveniently reasonably optimized. Through set simulations without crosswind, optimal obtained. Finally, tests under conditions 20 kn crosswind ±5° original drift angles were conducted configured . Accroding results, controller give performance.
