Nonlinear Robust/Adaptive Controller Design for an Air-Breathing Hypersonic Vehicle Model (Preprint)

Abstract

This paper describes the design of a nonlinear controller for an air-breathing hypersonic vehicle. To overcome the analytical intractability of this model, a nominal control-oriented model is used to derive the control law. The nominal model has unstable zero dynamics with respect to the output to be controlled, namely flight path angle and velocity, and presents intricate couplings between the engine dynamics and flight dynamics. The flexible effects have not been included in the analysis yet. Adaptive control techniques and robust control techniques are applied to achieve tracking of velocity and altitude trajectories. Simulation results are provided to show that the derived control law allows to achieves excellent tracking performance on the nominal model.
