量化非线性网络控制系统的建模与分析

Modeling and Analysis of Nonlinear NCSs With Quantization

研究了一类量化非线性网络控制系统.将网络控制系统的时延看成是分段时变的网络时延,利用T-S模糊模型的方法来设计非线性网络控制系统的模型,并在模型建立过程中考虑传感器与控制器以及控制器与执行器之间两个量化器的影响.系统的稳定性条件可以表示成一组线性矩阵不等式的形式.最后通过数值例子来例证所述方法的有效性.

This paper is concerned with a problem of quantitzed control for a class of nonlinear NCSs, which can be represented by a T-S fuzzy model with interval time-varying network delay. The influence between sensor and controller, and that between controller and implementor are taken into consideration during the process of model building. The conditions for the system stability can be represented by a set of LMIs. To illustrate the effectiveness of the proposed method, a numerical example is provided.
