Advances in high-speed real-time multi-rate simulation techniques for ship power systems

Real-time simulations of modern power electronic systems require very short frame times of the order of a few microseconds or less. Recent research has developed techniques using digital signal processors or field-programmable gate arrays to meet this need. Integrating these high-speed simulations in a complete power system simulation often requires multi-rate simulation techniques and integration of the high-speed platforms with conventional platforms based on a real-time operating system such as a real-time version of Linux.
