Abstract

The paper analyzes the vibration of an active suspension device using
adaptive fuzzy control (AFSCM) law under earthquake excitation. This is a
possible method to control the vibration of the top-layer for a active two-layer
suspension system. The fuzzy sliding mode is combined with adaptive law to
suppress the device's top-layer vibration against earthquake excitation. The
stability of the control method is guaranteed by Lyapunov theory. Numerical
simulations consider the proposed controller's performance on active control of
the proposed seismic device subjected to typical earthquake excitations. The
results indicate the effectiveness of the proposed method to reduce the vibration
of the top layer under some kinds of earthquakes.
