Abstract

This paper is a trial to establish global results for inverse simulation technique as applied to aircraft. This work builds on a previous result for rigid aircraft inverse simulation and adds a new level of complexity, that the aircraft is subjected to external sudden disturbances. The external sudden disturbance cannot be ignored even in the most basic flight conditions, thus the feed back will overcome this disturbances effects on aircraft dynamics and interprets that into modification of the control inputs. The technique was applied to some interesting two dimensional and three dimensional maneuvers.
