INTELLIGENT MODELLING METHOD OF COMPLEX CONTROL SYSTEMS AND ITS APPLICATION

The increasing demands for control of complex dynamical systems with significant uncertainty and nonlinear has made conventional system modelling methods which are based on differential equations,transform functions and state equations,very difficult and insufficient.This paper presents an intelligent modelling method that integrates the idea of artificial intelligence into traditional modelling of automatic control systems.The method in which the first order predicate representation is used,is very simple and feasible,and can be applied to describe complex systems modelling which is not only suitable for conventional control systems,but also for intelligent control systems,e.g.expert control systemso fuzzy control systems and control systems based on neural networks.The intelligent modelling provides a convenient approach to analyze complex systems and study the features of systems with intelligent control.
