Expert System Approach of Industrial Process Adaptive Control

This paper develops intelligent control from the view of integrating artificial intelligence with control theory, especially expert system with adaptive control. The general structure of intelligent control based on the principle of expert system is presented and is called Expert Intelligent Control (EIC). Expert intelligent control is the harmonious combination of dynamic inference, feature recognition, self-learning and control theory under knowledge base environment. In this paper, we also discuss the application of the real-time expert intelligent control for the tension control of an optical fibre drawing process. The EIC system is implemented in a microcomputer. The good operating results of the closed-loop control system show that our EIC scheme satisfies the requirements of the tension control system perfectly.
