英文摘要: In this project, the complex nonlinear interconnected large-scale systems with self-learning fuzzy hyperbolic modeling strategy and the networked decentralized control method are investigated. The overall framework integrating multiple theories and technologies is established, which include networked control system, fuzzy modeling and control for nonlinear interconnected large-scale systems. Main research contents are given as follows: ① Considering uncertain, mutually exclusive and coupling redundant informations, dynamic self-learning fuzzy hyperbolic modeling (FHM) strategy and implement method based on intuitionistic uncertainty-rough sets reduction algorithm are proposed; ②Networked control policies with dynamic buffer and network compensation are designed. Simple and useful compensation strategy and implementation method for uncertain network factors are developed; ③ Considering characteristics of fuzzy interconnected large-scale systems, the relation of robust stability and networked control performance index is established, and new intelligent robust control thought is formed. Novel methods are proposed about FHM-based networked controller structure, control algorithms and its implement strategy to improve the control performance for fuzzy interconnected networked control systems; ④ For different failure
