基于有限元正交配置法的动态数据校正技术,用于非线性动态系统的数据校正效果很好,并且可以求解具有代数不等式约束,或者是简单的变量上下限约束的问题。本文研究了有限元正交配置法动态数据校正技术的原理及应用方法。结果.当配置点数不小于3时,对校正精度的影响较小;但有限元数目不同,则有影响,因此,采用此方法应首先确定适合的有限元数目。
The dynamic data correction technology based on the orthogonal configuration of the finite element method has good effect on the data correction of the nonlinear dynamic system and can solve the problem of algebraic inequality constraints or simple variable upper and lower bound constraints. In this paper, the principle and application of the dynamic data correction technology of the finite element orthogonal configuration method are studied. Results When the number of configuration points is not less than 3, the effect on the correction accuracy is small. However, if the number of finite elements is different, it will be affected. Therefore, this method should first determine the suitable finite element number.
