摘要
由于现代工业的发展,其系统变得越来越复杂,传统的针对具体对象的建模方法已很难满足对其建模的需要。模块化建模方法逐渐为人们所推崇。但其在建模过程中也存在系统变量间的耦合问题。文章在对该建模思想进行介绍的基础上,采用一种引入状态变量的方法来解决这一问题。通过状态变量在某一时刻的值来求解系统其它变量,进而反过来修正状态变量在下一时刻的值,如此循环来求解系统,这样避免了用迭代法来解耦,提高了计算效率和仿真实时性。用这种方法在通用仿真平台上开发的模块,其使用范围更加广泛。
With the development of modern industries, the systems used in them have become more and more complex. The traditional modeling method dedicated to a specific system is hard to meet the need for modeling such systems. The modular modeling method is gradually used. But there also exists the coupling problem in the modeling process when people use this method to model systems. This paper will take the following measures to solve this problem after an introduction of the modular modeling method： it will introduce some variables called state variables into the modeling of the system, and then uses the value at a given time to calculate other system variables. When the other system variables are calculated, they will be used to get the values of the state variables for the next step. Such cycle continues and the system model is solved. This method can avoid using the iterative method to solve the coupling problem and improve the efficiency of calculation and the effect of real time simulation. The modules developed by this method on the general simulation platform can be widely used.
