Abstract : "This paper proposes a new fuzzy preview control method for an electro-hydraulic suspension system to
further improve the suspension performance and extend the results to practical situations that use the actual actuator
in a preview suspension system. A new augmented system that includes hydraulic actuators and preview information
of road disturbances is proposed and described by the T-S fuzzy system. Based on the parallel distributed
compensation (PDC) and multi-objective H∞=GH2 control design scheme, the fuzzy preview controller is designed
for a newly obtained model in which the closed-loop suspension system is asymptotically stable with guaranteed
robust performance in the H∞ sense. The simulation results clearly validate the effectiveness of the proposed controllers
in terms of its suspension performance."
