Semi-active suspension with semi-active inerter and semi-active damper [PDF]
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2014 Abstract This paper investigates the application of semi-active inerter in semi-active suspension. A semi-active inerter is defined as an inerter whose inertance can be adjusted within a finite bandwidth by on-line control actions. A force-tracking approach to designing semi-active suspension with a semi-active inerter and a semi-active damper is ...
