针对存在随机时延现象的一类网络化非线性系统,基于T-s模糊模型和Bernoulli随机序列,提出一种模糊网络滤波器的设计方法。给出了以线性矩阵不等式描述的模糊网络滤波器存在的充分条件,该条件保证所设计的模糊滤波器满足滤波误差系统均方指数稳定,同时满足期望的耗散性能指标。仿真结果表明,提出的方法能有效解决存在测量数据随机时延非线性系统的滤波器设计问题。
Based on Takagi-Sugeno (T-S) fuzzy model and Bernoulli random binary distribution technique, the problem of designing a dissipative fuzzy networked filter for a class of nonlinear systems with stochastic delays is studied. A linear matrix inequality (LMI) approach is developed to obtain the parameters of a fuzzy dissipative filter, which guarantees that the filter error systems are exponentially mean square stable and strictly dissipative. A numerical example is provided to illustrate the developed design.
