模糊随机广义系统的非脆弱H_∞控制

Non-fragile H_∞ control for fuzzy stochastic singular systems

利用模糊T-S模型对非线性随机广义系统进行分析,由Laypunov泛函方法,通过求解线性矩阵不等式得到了具有非脆弱性的H∞反馈控制器的显性表达,保证闭环系统是随机允许的且满足H∞性能指标.最后利用一个单种群随机广义经济系统的例子说明了定理的有效性.

This paper focuses on the analysis of nonlinear stochastic singular systems by T -S fuzzy models . A non-fragile H∞ feedback controller is considered , and the controller is constructed such that closed -loop systems are stochastically admissible and the H∞ performances are guaranteed .An example of single -species stochastically bioeconomic singular system is presented to show the validity of the proposed method .
