According to the lack of the part of the equipment design parameters of a certain type of ship power systems, the algorithm of recursive least squares for model parameter identification is studied. The mathematical model of the propulsion motor is established. The model parameters are calculated and simulated based on parameter identification method of recursive least squares. The simulation results show that a more precise mathematical model can be simple and easily obtained by using of the method.

Aiming at the characteristic of power system of modern ship, the components, software and hardware configuration, main function and feature of power system simulators are presented. Then the framework, simulation software and development of modeling technology are analyzed. At last, the improvement of instructor station and the application of VR technology for marine engine simulation are raised.

Based on the real requirements of ship navigation training simulation, a method of integration of AIS and ship navigation training simulation system was presented. The component and function of ship navigation training simulation system was introduced at first. And then the type and format of AIS information is analyzed. The AIS information simulation method is illuminated, the AIS information is send through serial port by the coach console, the AIS information is simulated by coach commander based on the receive message of AIS. The test result shows that the method presented in this paper can meet the requirements of integration of AIS and ship navigation training simulation system, and can also be able to satisfy the training demand of crews onboard.

The traditional submarine voyage training has problems of high cost, long period and high risk. In this paper, a submarine voyage training simulation system was proposed based on virtual reality and submarine control theory. At first, the construction of the system and the functions of modules were described. The coach control system based on digital chart was realized, which can achieve functions of training environment and parameters setting. The model library of virtual ocean scene was built and then the scene was rended by Vega Prime. In order to remedy the deficiency of the network, a DR algorithm was explored, which can satisfy the realtime requirements of scene simulation and achieved the frame alignment between channels and coherence of observers.
