Abstract
This article presents a study on the improvement of an existing longitudinal control law for in-use flexible aircraft using a powerful gain-scheduling technique that is multimodel eigenstructure assignement with self-scheduled dynamic feedback. The main objective is to desensitize the aircraft structural response with respect to the frequency variations of the first bending mode for an extended flight domain in order to ensure handling qualities specifications and passengers' comfort in turbulence.
