Abstract:
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 $H_\infty$-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.
