Mixed-μ-Analysis for Flexible Systems. Part II: Application to the Spot Family of Earth Observation Satellites

摘要

Mixed-m analysis of the companion paper (Magni et al., 1999) is a new tool introduced to support the control system design process on complex, multivariable flexible dynamic systems. In the present paper the transfer from research to applicationis described. The example retained is the SPOT satellite developed at MMS for earth imagery. The specificities of flexible large Space structures are correctly accounted for by the new tools, as they offer the capacity to track very narrow resonant peaks. All known as well as nonintuitive though meaningful worst-case combinations were discovered.
