Award. Dan delivered the 2012 SAE Buckendale Lecture on “Multi-Axle
Vehicle Dynamics.”
Abstract: Active suspension was a topic of great research interest near the
end of the last century. Ultimately broad bandwidth active systems were
found to be too expensive in terms of both energy and financial cost. This
past work, developing the ultimate vehicle suspension, has relevance for
today’s vehicle designers working on more efficient and effective
suspension systems for practical vehicles. From a control theorist’s BIOMED KEYNOTE
