Robust model predictive controller design for a Hypersonic Flight Vehicle

This paper considers the control problem of cruising flight of Hypersonic Flight Vehicle (HFV). The dynamic characteristics of HFV can be addressed as a strong nonlinear, and parameter uncertain multivariable system with hard constraints, which is extremely difficult to design the controller. In this paper, the longitudinal dynamic model of HFV is studied. Subsequently, we propose a robust model predictive control (RMPC) strategy to handle constraints in a systematic manner and overcome the impact of parameter uncertainty on the control effect, and a robust model predictive controller is designed for cruising flight of HFV. Simulation results show that this method can provide sufficient robustness and handle constraints effectively.
