Abstract

The authors propose a self-powered active control system, which realizes active vibration control using energy regenerated by an energy regenerative damper and does not require external energy. In this paper, the self-powered active control is applied to the anti-rolling system for ships. The motor is required to act as an energy regenerative damper and an actuator, since the anti-rolling system is composed of one motor. The new control scheme that realizes the self-powered active control with a single motor is proposed. Through numerical simulations and experiments on a basic model, the performance of the proposed system is examined. The results indicate that the self-powered active control can be achieved in the anti-rolling system.
