摘　　要：研究了有未知干扰的互联系统的H∞网络控制。考虑到网络控制时滞和数据包丢失的问题,使用T-S模糊模型对互联系统进行建模。基于LMI方法,根据李亚普诺夫稳定性理论和互联系统的分散控制理论,提出使该互联系统渐进稳定的充分条件,并且满足H∞性能指标。最后通过仿真实例验证了所提方法的有效性。The problem on Hoo control for network interconnected system with unknown disturbance was discussed. The Takagi-Sugeno （T-S） fuzzy model was adopted for fuzzy modeling of the network interconnected system, considering the problems on time-delay and data packet dropouts as networked control. According to the Lyapunov stability theory and decentralized control theory of interconnected system as well as based on LMI method, the sufficient condition that ensures the asymptotic stability and satisfies the H∞ performance, was proposed. Finally, the numerical examples in practice and simulations have verified the validity of the method.
