Active control shows superior performance compared with passive control or semi-active control, however, safety concern about active control in case of an electricity shortage is one of the disincentives to install it. In addition, it is required that amount of energy used for control is as small as possible with required performances in terms of energy saving and downsizing of vibration control device. In this study, focusing on an energy optimal control that considers consumption energy directly in cost function, its effectiveness of energy saving and performance are verified. The control method is applied to vibration control for a seismic floor isolation which is actively controlled. Most of the duration time power added to an actuator shows minus value, which means energy regeneration, using the energy optimal control. As a results, superiority of the energy optimal control in energy saving is confirmed by being compared with Linear Quadratic Regulator. Additionally it is shown that the energy optimal control is able to reduce responses as effectively as Linear Quadratic Regulator.
