This paper explores the unique design characteristics of automatic control systems in the presence of environmental disturbances. Specifically, the study focuses on controlling the movement of a marine vehicle along a predetermined course, despite unknown external events. Emphasis is placed on attaining the necessary closed-loop system attributes, such as the required stability margins. Furthermore, this study examines the means by which the marine object is stabilized via control, taking into consideration external forces, potential disruptions and additional stability margins.
