With the rapid development of the marine industry, research topics have become increasingly specialized, and the development of ship systems often requires the close collaboration of multiple teams. To meet the needs of online simulation and collaborative development for remote teams, a simulation model for optimizing the speed regulation system of marine diesel generator sets was constructed. Using MATLAB Web App technology and Java Web technology, an online simulation experiment platform was developed. The optimization simulation model of the speed control system and its synchronous demonstration operation were packaged into a MATLAB Web App, enabling online sharing, interaction, and deep integration of the simulation model. Practice shows that the online simulation platform allows for the customization of simulation parameters, smooth remote execution of simulation models, real-time observation of simulation results, significantly improving the development efficiency of remote teams, reducing the time and cost of repeated development, and providing an efficient and flexible solution for team collaboration.
