Abstract

The semi-active suspension system is getting widely accepted for its potential to improve ride comfort with low cost and light weight. A key to the success is to develop practical controllers that yield performance enhancement over the passive damper under various driving conditions. To this end, several control strategies have been studied and evaluated in this research in consideration of practical aspects such as nonlinearity and dynamics of the damper. From simulation results, it was observed that ride comfort can be significantly upgraded while suppressing degradation of driving safety at wheel resonance frequency.
