摘要
讨论了具有时滞关联的模糊大系统的分散镇定问题,基于李亚普诺夫稳定性理论及大系统分散控制理论,给出了保证该时滞模糊大系统闭环渐近稳定的LMI形式的充分条件。满足这些充分条件的分散化并行分布补偿(DPDC)控制器参数可通过MATLAB的LMI工具箱有效地求取。因此本文提供了一个综合时滞关联模糊大系统DPDC模糊控制器的有效方法。
Decentralized stabilization problem of fuzzy large-scale systems with time-delay in interconnections is considered in this paper. Based on Lyapunov stability theory and decentralized control theory of large-scale system, LMI-based sufficient conditions for asymptotic stability of the closed-loop fuzzy large-scale systems with time-delay are given, and the DPDC (Decentralized Parallel Distributed Compensation) fuzzy controllers satisfying these LMIs can be found efficiently via LMI toolbox in Matlab software. So an efficient method for synthesis of DPDC fuzzy controllers for fuzzy large-scale systems with time-delay in interconnections is provided in this paper.
