TWO-LEVEL CONTROL OF MULTTVARIABLE FUZZY SYSTEMS

摘要

The paper considers the application of the fuzzy linguistic approach in large scale systems control . Some definitions, regarding the decomposed subsystems and the respective local fuzzy variables, are given. A method of hierarchical fuzzy control is proposed in which the control actions have two components: local and global. The method is used for simulating the behaviour of an urban traffic network and the results are analysed. The number of fuzzy relations is significantly reduced and the real time control implementation is facilitated.
