Abstract: A
new control scheme, the hybrid fuzzy control method, for active
damping suspension system is presented. The scheme is the result
of effective combination of the statistical optimal control
method based on the statistical property of suspension system,
with the bang-bang control method based on the real-time
characteristics of suspension system. Computer simulations are
performed to compare the effectiveness of hybrid fuzzy control
scheme with that of optimal damping control, bang-bang control,
and passive suspension. It takes the effects of time-variant
factors into full account. The superiority of the proposed
hybrid fuzzy control scheme for active damping suspension to the
passive suspension is verified in the experiment study.
Key words: Semi-active
suspension Hybrid fuzzy control Simulation Experiment
