Study on Real-Time Simulation System

The real-time simulation system consists of simulation computer, physical effect divice and interface device. Its principle is that simulation computer computes various parameters of dynamics and envionment numerical model, measure circumstance that sensor required is generated through physical effect equipment, so the closed simulation system is established. The real-time simulation system is connected to practical system, so to avoid the error of complex system modeling and guarantee the real-time simulation system. There are advantages as well as large step and coincidence of message and the real-time input in the system, its major algorithm are Adams-Bashforth, Adams-Moulton, BK and so on.
