Design of passive suspension system to mimic fuzzy logic control active suspension system

Abstract Background This paper proposes a method for designing passive suspension system that determines the optimal settings while offering feasible performance near an active system. A mathematical model of nonlinear quarter car is developed and simulated control optimization in MATLAB/Simulink ® environment. The input road condition Class C Road, vehicle moves at 80 kmph. Fuzzy logic (FLC) action used to accomplish control. An approach investigating based on FLC force described here. optimized supposed have same travel velocity as least square technique implemented optimize parameters Results initial system, are It observed RMS acceleration 0.5057 m/s 2 , which reduced by 46% (passive has 0.9322 uncomfortable). For 0.6990 . almost mimics sprung mass VDV improved 30% 27%, respectively, compared Conclusion Also, health criterion-based results other systems.
