| 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,提出一种新的具有随机时廷的网络控制系统的建模方法--离散T-S模型,并在此基础上应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)研究系统的稳定性问题,给出了基于LMI的模糊控制器的设计方法.最后通过仿真实例验证了该控制方法能使具有时延的网络控制系统稳定.

| Abstract: | Aimming at networked control systems(NCS) with random time-delay,and according to the actual time-delay,this paper designs a networked control system's discrete model and proposes a fuzzy stable controller based on parallel distributing compensation theory.The design method of membership function is presented.Lyapunov theory and linear matrix inequality method are used to derive the sufficient conditions for the stability of NCS.A simulation example illustrats that the proposed method can guarantee the stab... |
