船舶动力装备CPS多维度统一建模及仿真优化策略研究

The Large marine power machine is a small batch customized Cyber-Physical System (CPS) which is a integration of computation, communication, control with discrete asynchronous information systems and continuous synchronous physical processes. A new design approach, which have high model reusing and unified modeling ,should be built for marine power machine, with an increasing demands for individuation, delivery time, and so on. In allusion to product design phases of marine power machine, model reusing method for different product desion phases, unified description, simulation and optimization methods for CPS models are studied in this project. In view of similarities and differences of design models in different design phases,a multi-design phases unified method is proposed to unified description for models of different design phases.In view of tight coupling of information and physical system in marine power machine, a unified modeling method is researched,and synchronization mechanism between time system and clock system is also researched to realize unified solution strategy of CPS model. In order to ensure the best design performance of marine power machine, optimization technique is studied for unified models. At last, a modeling and simulation prototype system will be structured for multi-phase unified design of marine power machine. Achievement of this project will lay foundation for basic theories of modeling and simulation for multi-phase unified design of marine power machine and provide the key enabling technologies.
