FREE ABSTRACT (to read the full article, please log in below).
In vehicle suspension design, an adaptive system is intended to deal with slow dynamic changes
corresponding to changes in road input conditions. However, the adaptation to the variation of vehicle
parameters is an important consideration in the switchable damper. This paper represents a self-tuning
control algorithm for vehicle suspension design. The controller provides the set of gains over different
operating conditions, and is based on the adapted estimates of vehicle parameters and states, and the
adapted weighting parameters. A quarter car model for the switchable damper suspension system is used.
The effect of extreme cases with a fixed gain controller for the switchable damper suspension system is
investigated. The proposed self-tuning system was used to control the switchable damper suspension system.
The results showed that the switchable damper with self-tuning gives a significant improvement over
fixed gains and passive suspension system.
