On fundamental limitations for rudder roll stabilization of ships
Goodwin, Graham C., Perez, Tristan, Seron, Maria, & Tzeng, Ching Yaw (2000) On fundamental limitations for rudder roll stabilization of ships. In Proceedings of the 39th IEEE Conference on Decision and Control (Volume 5), IEEE, 12-15 December 2000, pp. 4705-4710.
The main purpose of the rudder in ships is course keeping. However, the rudder can also be used, in some cases, to reject undesirable wave produced rolling motions. From a fundamental point of view, the main issues associated with this problem are the presence of a nonminimum phase zero and the single input two output nature of the system. In this paper, the limitations imposed on the achievable closed loop performance due to these issues are analyzed. This gives a deeper understanding of the problem and leads to conclusions regarding the inherent design trade-offs which hold regardless of the control strategy used.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
