The paper presents the static non-linear model with feedbacks of a freezing complex of a ‘Horizont’-type fishing trawler. The changes in specific power consumption for freezing fishery products in various operating regimes of a freezing complex have been analysed. The dynamic model of the compressor complex and the compressor operation local control system have been designed and analysed. Based on a static model of a ship’s freezing complex, the dynamic multidimensional model has been designed and analysed. It includes a freezing chamber air temperature and coolant condensation temperature automatic control system, and accounts for lags in the actuating paths. The self-learning system of extrapolative search of minimum the specific energy consumption for freezing has been designed. The microprocessor implementation of integrated automatic control system of a ship’s freezing complex has been offered. The necessary software providing for the required control system’s algorithms has also been designed.
