Gain-Scheduled Output Feedback Flight Controller Design via Non-Conservative Condition for Overbounding Parameter Discrepancies
This talk tackles the design problem of gain-scheduled output feedback controllers using inexactly provided scheduling parameters, and proposes a design method in which the overbounding condition for the discrepancies between actual and provided scheduling parameters is derived in a non-conservative way. In the last decade, this problem has been addressed intensively; however, the methods in literature are merely sufficient with respect to the overbounding of the discrepancies between actual scheduling parameters and provided ones. For this issue, we use a well-known ``Elimination lemma'' to overcome the bottleneck and provide a design method in which conservatism for overbounding the discrepancies disappears. The derived condition is still a bilinear matrix inequality; however, it's tractable compared to the original condition. We design a gain-scheduled flight controller for the lateral-directional motions of our research aircraft using our method, which well illustrates the effectiveness of our method compared to the methods in literature.

Dr. Masayuki Sato of JAXA (Japan Aerospace Exploration Agency)
Gain-Scheduled Output Feedback Flight Controller Design
Biography:
Masayuki Sato received his B.E. and M.E. degrees in aerospace engineering from Nagoya University, Japan, in 1995 and 1997, respectively, and Ph.D. degree in aerospace engineering from The University of Tokyo in 2009. Since 1997, he has been with the National Aerospace Laboratory (presently, Japan Aerospace Exploration Agency) as a researcher. His research interests include robust and gain-scheduled controller design, and their applications to flight controllers. He has been involved in several programs to develop Unmanned Aerial Vehicles (UAVs) and a Europe-Japan research collaboration project “VISION” for fault tolerant flight controller design.
