Abstract
Active vibration control using regenerated vibration energy, i.e., self-powered active vibration control is proposed in which energy absorbed by a damper is stored in a condenser. An actuator produces control input using this stored energy. This requires no external energy. Energy used by the actuator is restricted to be less than energy regenerated. It is important to reduce energy consumption in the actuator. The control we developed requires less external energy than typical active control. A linear DC motor operating as an energy regenerative damper with high efficiency is used in experiments realizing self-powered active control and showing better isolation than passive control.
