Recent advances of motion control technologies make it possible to realize intelligent machine systems. Mobile system such as an electric wheelchair is one of them and it is expected as a support instrument in the future aging society. This paper focuses on a development of electric wheelchair that ride quality becomes high. To address this issue, a vibration control strategies of wheelchair is proposed by using the variation of a rider's COG and resonant ratio control. The validity of the proposed strategy is confirmed by numerical and experimental results.
