Abstract

This paper presents new vibration control system using acceleration for ultra-compact mobility. 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. It is necessary to install small vibration control device to ultra-compact mobility. Therefore, active seat suspension is proposed for improving ride comfort of ultra-compact mobility. The actuator, voice coil motor, is connected seat surface, and control vibration of seat directly. In active seat suspension, accelerometer is used for measuring vibration. In generally, Velocity and displacement is fed back for vibration control. It is necessary to process acceleration signal for calculating velocity and displacement. Control system that fee back acceleration directly is required to improve control performance. In this study, acceleration feedback control system is proposed, and effect of control system is investigated by simulation.
