Abstract: With the view of automatic program for real time simulation of complex dynamic systems which can be of nonlinear and time variable characters, a study is made on automatic model generation of real time simulation. At first, a hierarchy to express the mathematical model of complex dynamic systems is proposed. Then, reference assignment relations among model variables and parameters in real time simulation software are discussed, and a frame which describes the reference assignment relations is introduced. The frame includes all the information required to transform a mathematical model into real time simulation software automatically, so the real time simulation model of complex dynamic systems can be expressed as a set of the frames. Based on the frame, a real time simulation model database and an automatical model generation system of real time simulation for complex dynamic systems are constructed.
