基于离散T-S模糊模型的非线性网络控制系统的镇定

在考虑了数据丢包和网络诱导时滞情形下,研究了一类非线性网络控制系统的镇定问题,其中被控对象是由一个离散T-S模糊模型描述的.利用平行分布补偿技术,建立了这类非线性网络控制系统的一个新的模型,得到了该系统稳定的充分条件,给出了基于线性矩阵不等式的模糊控制器的设计方法.数值例子说明了结论的有效性.

Stabilization for Nonlinear Networked Control Systems Based on Discrete T-S Fuzzy Model

This paper addresses the stabilization problem for a class of nonlinear networked control systems(i, e. , non-linear NCSs),which both packet losses and network-induced delay are taken into account. The controlled plant is a nonlinear system which is represented by a discrete T-S fuzzy model. Using the parallel distribute compensation (PDC) scheme,a new model for such nonlinear NCSs is established. Based on the model,a sufficient condition is de-rived to guarantee the stability of the nonlinear NCSs and a fuzzy controller design is proposed in terms of linear ma-trix inequalities(LMIs). A numerical example is given to illustrate the effectiveness of our results.
