Off-Line Offset-Free Output Feedback Model Predictive Control for a Constrained Hypersonic Vehicle Using Polyhedral Invariant Sets

An off-line offset-free output feedback model predictive control (OFMPC) is investigated for a generic hypersonic vehicle (HV) under interferences and parameter uncertainties. Off-line, the disturbance model is constructed, a nonlinear observer and the predictive control laws are designed. On-line, the MPC law is obtained by searching the minimum polyhedron set containing the translation state. Simulation results show that the given reference values of velocity and altitude can be tracked accurately even in the case of uncertain parameters and external disturbances.
