Intelligent control of large time-delay system based on fuzzy strategy

Abstract

Aiming at the problem of traditional Smith predictive control depending on the accurate mathematic model, a kind of intelligent control method for large time-delay system based on fuzzy strtegy is proposed and the intelligent self-adaptive-correcting controller that is suitable to the large time-delay system is designed. Dynamic and static performance, robust performance, and anti-interference performance of the intelligent contol system are discussed. The simulation results show that the self-adaptive-correcting characteristics of this intellingent control method is superior to those traditional control amd the quality characteristics and robustness of the system are improved. © 2011 Springer-Verlag Berlin Heidelberg.
