摘要: 给出了一种模糊控制系统的系统化设计方法,它采用一组局部T-S模糊模型来表 示模糊系统,对每个局部模型,利用状态反馈进行控制器设计,最后给出了全局模糊系统的稳 定性分析.通过对一个典型的非线性球-棒控制系统的仿真研究,表明该方法是有效的,它的 性能指标优于现有文献的结果.Abstract: A method of stability analysis and systematic design of fuzzy control is presented in this paper. Fuzzy control system is denoted by a family of local T-S fuzzy model with aggregation. The controller is designed by state feedback for each local model. Finally, it is shown that this controller guarantees global stability of the closed-loop fuzzy system. The simulation result of a nonlinear control system--a ball and beam system--shows that this method is effective.
