Abstract: According to the networked control systems with random time-delay problem,whose sensor node is time-driven,the controller and the actuator are event-driven,a new modeling method of Networked Control Systems-discrete fuzzy T-S model is proposed.And fuzzy controller by using parallel distributing compensation theory based on this model is designed.The stability of T-S model system by Lyapunov stability theory and linear matrix inequalities is analyzed.The controller design approach based on the LMI is presented.Finally a simulation example illustrating the proposed method is given.

摘要: 针对一类存在随机时延的网络控制系统,传感器采用时间驱动,控制器和执行器采用事件驱动,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-离散模糊T-S模型,在此模型的基础上应用并行分布补偿(PDC)原理设计了模糊控制器。应用Lyapunov定理和线性矩阵不等式(LMI)方法,研究了系统的稳定性问题,给出基于LMI的状态反馈模糊控制器的设计方法。通过仿真实例验证控制方法能够保证系统稳定。
