Anti-Rolling System for Ships with Self-Powered Active Control

The authors propose a self-powered active control system that realizes active vibration control using energy regenerated by an energy regenerative damper and does not require external energy. In this study, self-powered active control is applied to an 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 self-powered active control with a single motor is proposed. Through numerical simulations and experiments using a basic model, the performance of the proposed system is examined. The results indicate that self-powered active control can be achieved in the anti-rolling system.
