Batch Adaptive Rudder-Roll Control System

Abstract

One of the authors of this paper has developed the Roll Stabilization with Rudder Control by using Multi-variate Auto-Regressive Model. However, this system, which is of fixed gain type autopilot, has no abilities of being adaptable to the changing ocean conditions and the ship's dynamics. In this paper, this idea has been expanded in order to develop the Batch Adaptive Rudder-Roll Control System. Applying the on-line judgment procedure on a locally stational time series proposed by Ozaki and Tong, a practical adaptive rudder-roll control system can be desigend. The main content of this paper is to investigate the efficiency of the system and design of the Batch Adaptive Rudder-Roll Control System together with the results of experiments of the actual ship.
