Reliable robust flight tracking control: an LMI approach

TLDR

The paper investigates designing a reliable robust tracking controller for aircraft that tolerates actuator faults and control surface impairments. The authors develop a controller using mixed LQ/H∞ tracking performance and multiobjective LMI optimization to handle faults. Simulations on linear and nonlinear flight control examples demonstrate the controller’s effectiveness.

Abstract

This paper studies the reliable robust tracking controller design problem against actuator faults and control surface impairment for aircraft. First, models of actuator faults and control surface impairment are presented. Then a reliable robust tracking controller design method is developed. This method is based on the mixed linear quadratic (LQ)//H/sub /spl infin// tracking performance index and multiobjective optimization in terms of linear matrix inequalities. Flight control examples are given, and both linear and nonlinear simulations are given.
