Modeling of ship stability during changable regime of sailing

The paper deals with dynamic analysis of automatic ship steering gear systems utilizing complex controls that function according to the principle of proportional, integral and derivation regulators. The analysis involves a system dynamic simulation modeling methodology as one of the most suitable and effective means of dynamic modeling of complex non-linear, natural, organizational 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. The results presented in the paper have been derived from the scientific research project „ New Technologies in Diagnosis and Control of Marine Propulsion Systems“ supported by the Ministry of Science, Education and Sports of the Republic of Croatia.
