String Stability of Multiple Surface Marine Vessels

Abstract

The phenomenon of string instability is well known in a platoon of cars moving forward in an Automated Highway System (AHS). It is also known that ships can experience a similar instability phenomenon from mis-coordination of guidance and control laws. The proposed research studies the latter phenomenon, generalized in the case of multiple marine surface vessels moving in a platoon. The question of how it is possible for ships traveling in formation to exhibit the phenomenon of string instability is answered. Moreover, we examine under what conditions this phenomenon can be exhibited, as well as how it can be prevented.
