Abstract

ABSTRACT
In the paper, comparative analysis of the semi-active suspension systems
effectiveness towards the passive ones is studied. Several control laws are
investigated depending on the analyses goals–comfort increasing, stability
improvement or a realized compromise between them. There are suggested few
implemented controller types, and their effectiveness is discussed. The influence upon
the effectiveness of the damper nonlinear physical model is analyzed.
