本文提出了利用计算机模拟输出实施系统识别的方法,并把这种概念性方法称之为“计算系统识别”。其基本点是,用计算机仿真模型和方法替代通常系统识别研究中的真实系统(或模拟试验系统)和试验方法那一部分,而实现通常系统识别研究的原定目标。联系结构模型化工作,文中报告了一例安全壳结构弯剪梁模型的识别结果。文章还介绍了一个解有约束极小化问题的修正单纯形法,用以完成结构物理参数的寻优任务。
This paper proposes a method of using the computer simulation output to implement system identification, and calls this conceptual method “computation system identification.” The basic point is to use computer simulation models and methods instead of the real system (or simulation test system) and test method part of the system identification research, and to achieve the original target of system identification research. In connection with the structural modeling work, an example of the identification of a curved-shear beam model of a containment structure is reported. The paper also introduced a modified simplex method for solving constrained minimization problems to accomplish the optimization task of structural physical parameters.
