Active Rolling Control of Ships

Design of Control System in Consideration of Movable Range of Mass

Abstract

In this paper, we study the active rolling control of ships by active mass dampers. As the movable range of the mass on the ship is finite, the control system must include restriction on the mass position to protect the device and the ship. This restriction usually causes windup phenomenon and control performance is deteriorated seriously. We adopt anti-windup technique to improve the control performance and demonstrate its efficacy by simulation.
