Transportation which can be easily used is required in areas where public transportation is inadequate. Due to solve this issue, ultra-compact mobility is proposed. However, improvement of ride comfort for ultra-compact mobility is required. Therefore, active seat suspension is proposed for improving the ride comfort of ultra-compact mobility. The actuator, voice coil motor, is connected seat surface, and control vibration of the seat directly. Active seat suspension is a control system that vibration of the seat is controlled using the detected acceleration of seat surface. Generally, the feedback control algorithm, which uses displacement and velocity calculated by integration of measured seat acceleration, is applied in the control system of active seat suspension. However, a control delay and deviation due to the integration process could affect control performance. We focused on the vibration control system which fed back acceleration directly. Therefore, in this paper, the control system was analyzed to investigate control performance in the assumed actual road.
