Re-entry trajectory simulation for reusable launch vehicle

The subject is the design of a flight control system for a RLV by combining MPC with Feedback Linearization (FBL). The feedback linearization is based on the full rotational equations of motion rather than on a conventional model derived from time-scale separation. Input, and state constraints were applied to MPC algorithms to avoid input saturations, to guarantee a smooth tracking performance with non-linear rotational dynamics and a strong roll-yaw coupling of RLV model. The application RtFly Rapid Prototyping System has completed the re-entry trajectory real-time simulation model of 6-DOF simulation and the results demonstrate that the controller is able to better track the guidance parameters to meet the controller design specifications and real-time requirements.
