通过对系统的传递函数的两种转换差分方程方法的研究,引出对控制系统性能的考察,又利用LabView软件将两种差分方程的表现形式仿真出来,进而实现对系统的性能的考察,此后又对其中一种方法产生的误差进行分析并找出了产生误差的根本原因。

The damage identification is made by the numerical simulation analysis of a five-storey-and-two-span RC frame structure, using improved and unimproved direct analytical method respectively; and the fundamental equations were solved by the minimal least square method (viz. general inverse method). It demonstrates that the feasibility and the accuracy of the present approach were impoved significantly, compared with the result of unimproved damage identification. 展开更多
