Legacy-Based Design of the LISA Mission Science Control Mode

This article presents the design of the science control mode for the LISA mission using robust control synthesis methods and legacy information from the precursor technological demonstration mission LISA Pathfinder (LPF). The LISA mission will be the first space gravitational wave observatory. As such, it is characterized by very stringent scientific constraints resulting in unprecedented control challenges in terms of precision, accuracy, and complexity. Two robust control methods are used, the standard (full-order) and the structured (fixed-order) H-infinity approaches, and the results indicated that boths are excellent candidates to be used for the science control design of LISA.
