摘　　要：采用T-S模糊模型方法研究非线性网络控制系统的保性能控制问题。在系统状态不可得的情况下采用模糊观测器估计网络系统状态。利用并行分布补偿方法,根据合适的Lyapunov-Krasovskii函数建立基于模糊观测器的闭环系统鲁棒稳定的充分条件,该充分条件具有线性矩阵不等式形式,能够采用数值稳定的计算方法。仿真结果证明,所提出的控制器和观测器设计方法的有效性。In this paper, a guaranteed cost Takagi-Sugeno(T-S) fuzzy system method for nonlinear networked control is developed. When the state of the system cannot be directly measured, a fuzzy observer(FO) is proposed to estimate the plant states under the network environment. By selecting the proper Lyapunov-Krasovskii function, the sufficient condition for the robust stability based on fuzzy observer of the closed-loop system is obtained by utilizing the PDC technique and solving a set of linear matrix inequalities(LMIs). The simulation results indicate the validity of the proposed controller and observer.
