In this paper, an active suspension system for the exponential decay control of the three-degree-of-freedom (3DOF) twin-shaft vehicle is proposed. A new exponential stabilization criterion of the second-order vector differential equations is derived and the particle swarm optimization (PSO) method is employed for searching the optimal controller parameters. The proposed method guarantees all of states of the vehicle in an optimally exponentially decaying manner. The simulation results show that the vibration characteristics of the vehicle by the proposed active suspension achieve high performance in the control of the vehicle body vibration and provide higher driving safety than the passive and linear quadratic (LQ) active suspensions.
