复合模型中实时耦合问题的探讨

Real-time coupling in hybrid model

通过分析实时耦合复合模型中物模(物理模型)与数模(数学模型)的连接过程,指出:复合模型中的物模部分与数模部分的关系是相互制约、相互依存的,二者间的实时耦合以及耦合的精度是复合模型成功的关键;耦合的时间和空间匹配条件保证了复合模型中物模与数模两个部分连接的时空连续性;控制周期的大小、控制变量的选择以及控制的策略是影响复合模型耦合精度的主要因素,复合模型各部分都应以满足这些因素为前提进行设计.

Based on an analysis of the linking course between the physical model part and mathematical model part in the realtime coupling model, it is pointed out that the two parts are restricted by and depend on each other, and the realtime coupling and its precision are the keys to the hybrid model, that the conditions of time and space matching ensure the continuity of the coupling between the two parts, and that the control period, control variables, and control strategy are the main factors affecting the precision of coupling in the hybrid model. So the above factors should be considered when a hybrid model is built.
