The paper deals with dynamic analysis of automatic ship
steering gear systems utilising complex controls that function
according to the principle of proportional, integral and
derivation regulators. The analysis involves a system dynamic
simulation modelling methodology as one of the most suitable
and effective means of dynamic modelling of complex non-
linear, natural, organisational and technical systems.
The paper discusses system dynamics simulation models being
used in qualitative (mental-verbal, structural) and quantitative
(mathematical and computer) simulation models on ships
equipped with trailing steering systems and PID regulator.
Authors suggest using the presented models for designing and
constructing new steering systems, for diagnosing existing
constructions and for education in Universities.
