Nonlinear adaptive control design for non-minimum phase hypersonic vehicle models with minimal control authority

摘要: The design of a nonlinear robust controller for non-minimum phase model the longitudinal dynamics an air-breathing hypersonic vehicle is presented in this work. When flight-path angle selected as regulated output and elevator only control surface available pitch dynamics, models exhibit unstable zero-dynamics. approach proposed paper uses combination small-gain arguments adaptive techniques state-feedback that achieves asymptotic tracking velocity reference trajectories spite uncertainties. method reposes upon suitable redefinition internal control-oriented time-scale separation between controlled variables to manage peaking phenomenon occurring system. Simulation results on full illustrate effectiveness methodology.
