摘要
讨论了具有时滞关联的连续时间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工具箱有效的对其进行求取 .
Decentralized stabilization problem of continuous-time fuzzy large-scale systems with time-delay 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.
