To solve the ascent guidance of reusable launch vehicle (RLV) under the uncertain condition, a robust guidance method based on combing feedback linearization and H-infinity optimization theory is proposed. The article establishes the RLV ascending dynamic models. According to the characteristics of the ascending flight, the height deviation is converted into a linear relationship with pitch angle by feedback linearization, and combing H-infinity control theory to design guidance law, solving the trajectory tracking when the environmental parameters change significantly with respect to the reference trajectory. The simulation result shows that the height tracking can be realized by the guidance.
