Fuzzy gain-scheduling for MIMO systems applied to flexible aircraft control

Abstract

© Universal Technology Corporation, 2018.Previous works evidenced stability problems associated with flight control law design for flexible aircraft. In this paper, a fuzzy-based gain-scheduling approach is proposed to adequate closed-loop response. An interactive method that aims performance improvement while enforcing global stability considering fuzzy gain-scheduling was proposed. The application of the technique was demonstrated for the flexible X-HALE aircraft nonlinear model and compared to classical interpolation-based gain-scheduling techniques. Results revealed that fuzzy-based gain-scheduling is promising for flexible aircraft control.
