N2 - The vehicle suspension system must isolate or reduce the vibrations that occur in the vehicle body due to road disturbance. Series Active Variable Geometry Suspension (SAVGS) is a suspension system that offers much better performance than passive suspension and can overcome the disadvantages of active suspension. This study will discuss the effect of single link length on SAVGS, especially on comfort and road-holding performance. The suspension system is modeled as a quarter car, where the effect of a single link length is analyzed in the form of equivalent stiffness and damping. The linear quadratic regulator is considered for the control design. The control system's performance was tested on a non-linear model with road disturbances consisting of bumpy roads and highway roads. The simulation results show that the longer the single link, the greater the vehicle's comfort and road holding on the vehicle increase. However, the longer the single link, the more the control input is needed.
