Control redundancy as a quantitative measure of maneuverability

Abstract

The purpose of the article is to determine the criterion of control redundancy and calculate its value for various types of vessels and navigation modes. A brief review was carried out and it was concluded that redundancy controls are mostly used only as a backup to improve reliability, but not as a means of optimizing control. The dependence of the vessel’s maneuvering capabilities on the value of this criterion and its importance in the classification is shown. A formula for calculating control redundancy is proposed, and control redundancy values are calculated for vessels with different control schemes.
