Development of an Expert System for Computer-aided Control Systems Design

Abstract

We propose a rule-based expert system for computer-aided control systems design (CACSD). The main goals of this expert system are to reduce the users’ knowledge needed for operating CACSD package as much as possible, and help users to obtain satisfying design results. The expert system acts as an intelligent front end between the users and CACSD package. The expert system embodies knowledge not only about all the detailed syntax rules required for forming a CACSD running program, but also about particular problem-solving, command interpretation, control theory and alogrithms. The expert system decides what kinds of input are required for a problem-solving, and then prompts the users in a friendly fashion for any additional information. The expert system is a rule-based system, using data list structure to model the approaches and the attributes (i. e., problem attributes, approach attributes, and so on).The concepts, the thoughts and the new ideas we have described in this paper may be of great value in the development of the third-generation of CACSD package.
