一类非线性网络控制系统的随机H∞控制

研究了一类带有丢包的非线性网络控制系统(NNCSs)的随机H∞控制问题.丢包过程采用满足伯努利分布的随机序列来描述.利用T-S模糊模型和平行分布补偿技术建立了带有随机参数的非线性网络控制系统的模型,并以线性矩阵不等式的形式给出了模糊控制器存在的充分条件;所设计的控制器使得非线性网络控制系统在均方意叉下指数稳定且具有一个改进的随机H∞性能.

Stochastic H8 Control for a Class of Nonlinear Networked Control Systems

The stochastic H_∞ control problem for a class of nonlinear networked control systems (NNCSs) with packet dropouts was considered. The packet dropouts were modeled as a stochastic process satisfying Bernoulli distribution. Using T-S fuzzy model and PDC technology, the models for a class of NNCS with stochastic parameters were established. Moreover,a sufficient condition for the existence of a fuzzy controller is presented in terms of LMIs,and the controller made the NNCS exponentially mean-square stable and with a modified stochastic H_∞ performance.
