| 摘 要： | 针对网络控制系统(NCS)中的随机时延问题,根据实际网络时延的分布情况,提出了一种新的具有随机时延的网络控制系统的建模方法-离散T-S模型,并用并行分布补偿原理(PDC)设计模糊控制器.同时提出一种新的模糊控制系统隶属函数的确定方法,利用Lyapunov定理和线性矩阵不等式(LMI)研究了系统的稳定性问题,给出基于LMI的模糊控制器的设计方法.最后通过仿真实例证明控制方法能够使具有时延的网络控制系统稳定.

| Abstract: | This paper deals with Networked Control Systems with random time-delay.According to the actual time-delay,a Networked Control system's discrete model is designed and a fuzzy stable controller based on parallel distributing compensation theory is proposed.The design method of membership function is presented.The Lyapunov theoreom and Linear Matrix Inequality method are used to derive the sufficient conditions that guarantee the stability of NCS.A simulation example illustrates that the proposed method is fea... |
