ROBUST NONLINEAR CONTROLLER DESIGN FOR A LONGITUDINAL FLIGHT CONTROL PROBLEM

In this paper, the H∞ approximate I/O linearization formulation and µ-synthesis are employed to design a nonlinear controller for an aircraft longitudinal flight control problem. We propose modified nonlinear H∞ controller formulas to approximately linearize the system and use µ-synthesis to address tracking, regulation, and robustness issues.
