metadata.value: With the further development of the world economy, the corresponding transportation
  infrastructure has also brought about many problems, which, foremost, are associated with
  the traffic safety of vehicles. In particular, the issue of ship traffic safety has become even more
  important as maritime traffic continues to grow. The main attention in this article is given to
  the development of methods and the design of computational algorithms for the synthesis of
  multipurpose control in marine autopilots, the main purpose of which is to counteract the effects
  of sea waves in order to preserve the movement at a given course. Currently, various approaches
  are used for the design of autopilots, a large number of scientific papers have been published, but
  the problem of the synthesis of control laws for these systems has not been exhaustively resolved.
  First of all, this is due to their multipurpose mission, which determines the need for work in
  various driving regimes with conflicting requirements for the quality of dynamic processes. In
  this paper, we propose a new practically oriented method for the synthesis of control laws
  for autopilots, which is based on feedbacks with a multipurpose structure. However, these
  works of optimization approach had assumed that the initial data includes a known frequency
  spectrum of sea waves, the knowledge about which comes in the course of identification, realized
  in the system of adaptive autopilot reconfiguration. Naturally, such a consideration of the
  actual conditions of navigation significantly improves the quality of management processes.
  But adaptive reconfiguration, for lots of reasons, cannot always be applied in practice. For
  example, it may not allow enough time for the system’s operating conditions. To this end we
  have developed a simple constructive method for calculating the transfer function for a dynamic
  filter as part of the heading control law implemented by a marine autopilot. This method is
  based on the ideology H∞-optimization, which makes it possible to ensure a guaranteed quality
  of filtration when moving in sea waves. Unlike other widely used approaches, the indicated
  purpose will be achieved by using the specialized multipurpose structure of the control law.
  The approach has lot of advantages in comparison with alternative options, namely flexibility
  configuration in real conditions of navigation. The proposed approach can be expanded by
  applying it to control marine unmanned objects or floating offshore structures. Refs 11. Fig. 1.
