| 中文摘要 |
| 本文讨论了一种有效的软件误差分析法—摄动法，以及它在控制系统CAD软件包误差分析中的应用。文中首先给出了应用摄动法求任意数制有效位数的估算公式，然后利用本方法对MCSS**软件包中的主要算法进行了误差分析。经在PDP-11/23计算机上反复计算表明，用本方法来分析软件误差是有效的，所得的结果与实际情况相符。不仅如此，利用本方法还改进了矩阵奇异性的判据以及迭代算法的终止条件，从而改善了MCSS的软件质量。 |
| 英文摘要 |
| An effective error analytical method, the perturbation method, and its application to the control systems CAD software packages are discussed in this paper. Using the perturbation method, we first present the formula for estimating the significant digits in any numeration systems, and then analyse the errors of the main algorithms in MCSS. The results of repeated computations in PDP-11/23 show that the perturbation method is valid for software error analysis. Moreover, the detection condition of the matrix singularity and the stopping rule of the iterative algorithms are improved after using the perturbation method, and, hence, the quality of MCSS is improved. |
