A model for dynamic feed-forward control of a semi-active damper
Authors: Andreas Unger, Enrico Pellegrini, Kay-Uwe Henning, Boris Lohmann
Abstract
A new nonlinear model for a semi-active damper which describes a broad variety of hysteresis effects is presented in this paper. The novel part of the model is that the few parameters can be identified easily and cost effective for the automotive industry. Despite the few amounts of parameters, the validation of the model shows, that it describes the behavior of a real semi-active damper with strong hysteresis effects very well. Additionally, the influence of the unknown parameters is discussed in a detailed parameter study. In order to consider the hysteresis in the current control, the model is embedded in a dynamic feed-forward control structure.
