Abstract: The problem of construction of systems for automatic motion control of marine vessels is one of the main problems considered in the scientific publications of both theoretical and practical orientation. One of the most important requirements for such systems is astaticism on regulated coordinates, i. e. the ability of the system to guarantee a zero static error under the constant external disturbance. However, in addition to stabilization mode it is widely used another modes of automatic traffic control. In particular, considerable attention is paid to tracking control and dynamic positioning. The aim of the paper is the development of methods to provide the astaticism using the multipurpose structure control laws. The main focus is to expand the scope of their applicability to the task of tracking control and dynamic positioning. Bibliogr. 8. Il. 5.

Keywords: astaticism, control, stabilization, tracking control, dynamic positioning.
