| 摘 要： | 针对一类用T-S模糊模型描述的不确定离散非线性大系统,研究了其鲁棒非脆弱H_∞保性能模糊控制问题.基于Lyapunov稳定理论,得到一种通过状态反馈实现的非脆弱H_∞保性能模糊控制器.该模糊控制器能保证闭环系统稳定和一定的二次型性能指标上界,同时具有H_∞下的干扰抑制作用.数值例子仿真表明了该设计方法的有效性.

| Abstract: | This paper considers the problems of robust non-fragile H_∞ guaranteed cost fuzzy control for a class of uncertain discrete nonlinear large-scale systems described by T-S fuzzy model. Based on Lya-punov stability theorem,non-fragile H_∞ guaranteed cost fuzzy control was obtained by state feedback. The controller guaranteed the robust stability of the closed-loop system,and the upper bound of quadratic performance index satisfied the H_∞ disturbance attenuation level. A numerical example was given to illustrate the effectiveness of the proposed design. |
