Fin and rudder hybrid stabilization system

Abstract

Modern roll stabilization system, namely fin, anti-roll tank and rudder action are used respectively or in combination on most passengers and naval ships. This paper proposes the advanced rudder roll stabilization control system with fin control. Fin and rudder multivariate hybrid control system were designed using multivariate autoregressive model with multi-input (yaw and roll motion) and multi-output (rudder and fin angle), named MAFRCS (Multivariate Autoregressive Fin and Rudder hybrid Control System). This paper presents the results of studies which led to the development of performing mode of operation for this hybrid control system which system has full control of rudder while fin automatically reduce the roll motion and keep the yaw motion. The results of full scale experiments and simulations studies were given to illustrate the system performances.
