In this paper, the active suspension system is designed to reduce vibration on the passenger seat caused by change in road-surface shapes or disturbance. PID control is utilized in the design of this active suspension system, and Direct Synthesis method is proposed to tune PID parameters. Direct Synthesis method optimize PID tuning parameters to achieve desired output response in different road surface. In this study, three interference signals are used as disturbance from surface road i.e step, impulse, and sinus. The aim of the suspension control design is to obtain the control parameters that conform to ISO 2631. The simulation results show that value of τc 0.0002 for step disturbance provide aRMS 0.086 m/s2 and damping ratio 0.21. For impulse input the value of τc 0.002 provide aRMS 0.112 m/s2 and damping ratio of 0.22. For sinus input value of τc 0.00005 provide aRMS 0.09 m/s2.
