Dynamic Surface Control of Hypersonic Aircraft with Parameter Estimation
This paper investigates the adaptive controller for the longitudinal dynamics of a generic hypersonic aircraft. The control-oriented model is adopted for design. The subsystem is transformed into the linearly parameterized form. Based on the parameter projection estimation, the dynamic inverse control is proposed via back-stepping. The dynamic surface method is employed to provide the derivative information of the virtual control. The proposed methodology addresses the issue of controller design with respect to parametric model uncertainty. Simulation results show that the proposed approach achieves good tracking performance in the presence of uncertain parameters.
