TLDR
It is shown that the aircraft impact and vibration isolation properties of the dynamic response of motions can be improved and the highly nonlinear aircraft dynamics coupled with varying landing and runway conditions are handled with the proposed fuzzy controller.Abstract:
With respect to fatige life of both the landing gear and airframe and passenger comfort the good landing impact and taxi performances are becoming more important due to the increasing in life time and in taxi distancea of aircraft. This paper presents a semi-active landing gear system controlled with fuzzy logic. It ie shown that the aircraft impact and vibration isolation properties aa well e.a the dynamic response of motions can be aigoiflcantly improved. The highly nonlinear aircraft dynamics coupled with varying landing and runway conditions are handled web with the proposed fuzzy controller.read more
