SYNTHESIS OF AN OBSERVER FOR THE SHIP’S COURSE CONTROL SYSTEM

Digitalization of technological processes on ships using the tools of modern computing
systems allows solving important technical problems at a qualitatively new level, improving information
support and monitoring of the technical condition of ships and ship technical systems
based on dynamic observers and evaluators. A method for synthesizing observers for a ship’s course
control system based on the theory of modal regulators is considered. The models for assessing
the operational performance of ship control systems are based on the application of a generalized
mathematical model, which can take various forms depending on the influence of numerous factors
on its structure and parameters.
The adequacy of the dynamics of simple models and an object functioning in a changing external
environment can be improved with modern algorithms for analysis, synthesis and optimization of
automatic systems, tools of computing environments and computer technologies using the basic

provisions of modal control. The method of synthesis of a dynamic observer considered in the
paper is The Luenberger model of full dimension differs in that it takes into account the structure
of the matrix of the state of the ship model with the Ackerman regulator, which allows, subject to
the conditions of controllability and observability, the choice of the structure of the stabilizing part
of the observer matrix in the form of column vectors with non-zero elements, which significantly
simplifies the synthesis procedure. The regulator and observers were calculated to estimate the
vector of state variables of the supertanker with a deadweight of 150 thousand tons.
