Abstract: This paper analyses, from a control perspective, two physically different dampers for the semi-active control of ride: the magnetorheological damper (|conventional|) and the friction damper (|non-conventional|). An in-depth analysis will show that the latter damper has modelling and control analogies with the magnetorheological damper and has the potential to be a low-cost alternative to a controlled viscous damper in particular areas of application. A general variable structure algorithm targeted to achieve ride control has been designed and implemented on both dampers. A variety of automotive applications have been investigated to offer a more well-rounded vision of the applicability of such dampers.

Keywords: ride comfort; friction damper; magnetorheological dampers; road damage; seat suspension; semi-active control; variable structure control; vehicle suspension; smart damping systems; automotive ride control; tyre load oscillation; road damage; vehicle handling.
