Abstract

This paper presents a control scheme composed of a closed loop system consisting of a dynamic inversion inner loop controller and a proportional, integral, derivative outer loop controller augmented with either a reference or an extended command governor that is developed for very flexible aircraft flight trajectory control. The governors enforce curvature limits, which are directly proportional to bending moment, on a very flexible aircraft model following a flight path angle set-point command.
