最优控制理论和计算结构力学原是两个互不相关、独立发展的领域.最近发现:它们之间存在着一种对应的模拟关系.这一相似性原理的发现使得这两个领域的成果可以互相促进,特别是用计算结构力学解决最优控制问题已显示出独特的优越性,由此产生了一门模拟理论.本文简要地介绍一下该理论. The optimal control theory and computational structural mechanics are originally two fields that are independent of each other and have been independently developed. Recently, it has been found that there is a corresponding simulation relationship between them. The discovery of this similarity principle has resulted in the achievement of these two fields. Can promote each other, especially the use of computational structural mechanics to solve the optimal control problem has shown a unique superiority, resulting in a simulation theory. This article briefly introduces the theory.
