In this paper, a problem of ride comfort enhancement in a moving
vehicle was introduced and controlled by damping force to deduce
vibration caused by road profile. Sliding mode control was used to
give the damping force in two degree of freedom su
spension
system. A mechanic model of suspension system was given,
dampers and springs were used for passive damping to reduce
chattering and sliding mode control for semi-active control with
proposed method by using supervised fuzzy logic control for
chattering decreasing was designed.
A simulation with the given initial conditions was designed using
Matlab/Simulink. By computing of root mean square error we got
that the proposed method gave the best responses with the smallest
chattering compared with traditional mechanical damping and
sliding mode control. All results plotted using Matlab/Simulink.
