Dynamic Inverse Based Controller for a Hypersonic Flight Vehicle

Abstract

A dynamic inverse based controller is designed for the longitudinal dynamics of a generic hypersonic vehicle. This model is strong nonlinear, multivariable coupling and includes uncertain parameters based on its high speed, lager aerodynamic load and rapid changing flight area. After feedback linearization of original model to get dynamic inverse linear model, optimal control method is used to develop controller to follow height and velocity commands. Simulation studies demonstrate that this controller is capable to follow height and speed change commands rapidly and accurately with certain robustness.
