动态数据系统软件的移植、优化与调试

动态数据系统（ＤＤＳ）作为一种构思新颖的系统建模方法，在系统辨识领域里已日渐受到重视。本文结合我们的使用经验，介绍了ＤＤＳ软件在向ＩＢＭ－ＰＣ微型机上移植的基本思想．移植中遇到的特殊问题及其处理方法。利用软件工程中的ＳＤ方法，成功地获得了结构化ＤＤＳＤ软件。实际应用结果表明，ＤＤＳＤ软件不仅保留了ＤＤＳ软件的全部功能．而且优化了源程序结构与算法，扩充了软件的处理功能，特别是移植后的ＤＤＳＤ软件能方便地在ＩＢＭ－ＰＣ及其兼容机上运行。此外，本实践也为从事系统仿真研究的科研工作者在微型机上移植或开发大型系统仿真软件提供了参考。

PORTABILITY, OPTIMIZATION AND DEBUGGING FOR DYNAMICS DATA SYSTEM SOFTWARE

Dynamics Data System(DDS) has been increasingly taken into consideration in the domains of system identification as a new modelling method. In this paper,the basic ideas of portability, optimization and debugging for DDS software in IBM-PC microcomputer are introduced according to our own experience in use,some particular problems-and their solutions in portability are given as well. The structured DDSD software has been successfully gained by means of structured design in software engineering. The results in applications show that DDSD software has not only kept all merits of DDS software, but also optimized source programme structure and algorithm, extended some processing functions. Especially, DDSD software can be easily operated in IBM-PC microcomputer. Moreover,the studies in this paper provide valuable mode for the research workers being engaged in portability or development of large-scale system simulation software in IBM-PC or other microcomputers.
