Generally, the caster is attached to most medical equipments. However, in an earthquake, equipment with unlocked caster moves widely but if another one with locked caster gets large acceleration. In past study, for the purpose of reducing seismic response of caster wagon, Instantaneous Optimal Control with ER brake was proposed. And the effectiveness was confirmed in simulation and shaking experiment. But base torque of ER brake was a little high, that fine control was difficult. And weight coefficient used in optimal control needs to be changed manually depending on seismic acceleration. In this study, ER brake was changed to other one that has lower base torque. Additionally weight coefficient used in optimal control was discussed to improve control effect.
