Abstract: In this paper, the exerted force at next time is calculated by forecasting structures on line exerting, then this force is exerted on the structures. In this process of computation, a new kind of improved time precise integration method is given, which can be used for solving time-delay problem under random forces. The example shows that the method presented in this paper is effective for solving the time-delay problem in the structures.
Keywords: precise integration, feedback, time-delay.
