A Fuzzy Sliding Mode Controller of Real Vehicle Semi-Active Suspensions (Comparison with Output Feedback Sliding Mode Control)

摘要

The task of a suspension is to support the vehicle body and develop ride comfort, but if the attenuation force becomes large, the passenger will feel rigidity at high frequencies. If the attenuation force becomes small, the passenger will feel a softness at low frequencies. If the coefficient of spring becomes low the vehicle's natural frequency of vibration becomes low, thus the heave, rolling and pitching will become large.
