This paper discusses the problem of synthesizing robust controllers for reusable rocketsduring the aerodynamic descent phase. Emphasis is given to a well-established subset ofmethods, specifically robust control techniques based on the H concept. A thorough?description of how this family of methods can be used for the descent phase of reusablerockets is provided, together with a comparison of the full- and structured-version of H?methods. The methodology, the problem faced and the performance that can be obtainedare discussed. Some results are shown for CALLISTO, a reusable rocket demonstrator jointly developed by DLR, JAXA, andCNES.
