摘要
研究了一类非线性网络控制系统的控制和数值仿真问题。首先建立了非线性网络控制系统的连续时间T-S模糊模型。然后基于时变网络诱导时滞,分别设计了系统在无外部干扰和有外部干扰两种情形下的模糊控制器,同时以线性矩阵不等式(LMIs)的形式给出了控制器存在的充分条件。最后通过数值仿真验证了以上两种情形下控制器的有效性。
The control and numerical simulation for a class of nonlinear networked control Systems（NCSs） were investigated.The NCS was modeled by continuous time T-S fuzzy system.Based on time-varying network induced delays model,fuzzy controllers were developed respectively with and without disturbance.And the sufficient conditions for existence of controllers were given in linear matrix inequalities（LMIs）.Finally,the numerical example shows the efficiency of the proposed approach.
