Abstract

This paper addresses flight control system synthesis and the accommodation of controlled plant variation in an aircraft design envelope by using the frequency domain based quantitative feedback theory robust control system design method. The plant variations considered include varying flight conditions in the flight envelope and damage to aerodynamic control surfaces. A digital flight controller for the aircraft´s longitudinal channel is designed and validated with simulations containing nonlinear saturation elements
