摘　　要：在考虑了数据丢包和网络诱导时滞情形下,研究了一类非线性网络控制系统的镇定问题,其中被控对象是由一个离散T-S模糊模型描述的.利用平行分布补偿技术,建立了这类非线性网络控制系统的一个新的模型,得到了该系统稳定的充分条件,给出了基于线性矩阵不等式的模糊控制器的设计方法.数值例子说明了结论的有效性.This paper addresses the stahilization problem for a class of nonlinear networked control systems（i, e. , nonlinear NCSs）, which both packet losses and network-induced delay are taken into account. The controlled plant is a nonlinear system which is represented by a discrete T-S fuzzy model. Using the parallel distribute compensation （PDC） scheme,a new model for such nonlinear NCSs is established. Based on the model,a sufficient condition is derived to guarantee the stability of the nonlinear NCSs and a fuzzy controller design is proposed in terms of linear matrix inequalities（LMIs）. A numerical example is given to illustrate the effectiveness of our results.
