【Abstract】 The composing and function of hardware-in-loop simulation systems in dual-computers is presented in this paper, which analyzes the time resource and puts forward the synchronous startup scheduling mechanism. It also analyzes the mechanism of time delay, presents the compensation method and sums up its mathematics model. Application of the compensation mathematics model in the hardware-in-loop simulation experimentations shows the validity of the compensation method and the great increase of simulating precision. Furthermore, the compensation method can be used in LAN distributed simulation systems of the multi-computers as well to improve the simulation precision.更多还原
