摘　　要：文章采用T-S模糊模型描述非线性网络控制系统,针对该系统中存在的前向通道和反馈通道时延,采用史密斯预估器进行补偿;对非线性网络控制系统建立了T-S模糊模型,给出该模型的稳定模糊控制器存在的充分条件和模糊状态反馈控制器的设计方法,并给出相应的线性矩阵不等式形式和具有常数衰减度系统的稳定性存在的充分条件和相应的线性矩阵不等式形式;仿真算例结果表明,模糊状态反馈控制器的设计是行之有效的。Nonlinear networked control system is described as T-S fuzzy model,and delays that exist in forward channel and feedback channel of nonlinear networked control system are compensated by Smith estimator.T-S fuzzy model is built for nonlinear networked control system.Sufficient condition for existence of stable fuzzy controller,design method for fuzzy state feedback controller,and the form of linear matrix inequality are given.Sufficient condition for existence of stabilization for the system with constant exponential attenuation and the relevant form of linear matrix inequality are also given.The results of simulation show that the design of fuzzy state feedback controller is effective.
