毕业设计 基于T-S模型的模糊控制系统设计 基于T-S模型的模糊控制系统设计 摘　　要 模糊控制系统的稳定性分析和设计方法是模糊理论的重要研究课题。模糊系统本质上是非线性的，其稳定性分析比较困难。到目前为止虽然已经存在许多关于模糊系统稳定性的理论，但仍未形成完善的理论体系，还有许多理论问题有待进一步深入研究。 Model Based on the T-S Fuzzy Control System Design ABSTRACT The stability analysis and design of fuzzy control systems have been the most important problems in fuzzy theory. The research of fuzzy control theory includes a series of main problems, such as the stability analysis, the system design approaches and the improvement of system performance. In the fuzzy control literature, most methods are based on Lyapunov stability theory, Lyapunov system is stable form is the observing systems in the energy balance based. According to Lyapunov theory, the continuous energy loss of the system will eventually enter theory.Therefore, the use of the energy function of a system able to evaluate the stability of the system, This function is often referred to as the Lyapunov function or Lyapunov candidate function. The most commonly used form of Lyapunov function is a generalized quadratic. Since the Lyapunov is defined as the generalized quadratic, System stability problem is converted to the problem of finding an appropriate matrix. Based on the above analysis, for the TS model using Matlab fuzzy control system design, and a nonlinear spring-damper mechanical system simulation to ensure stability of the system Key Words: Lyapunov Function; Fuzzy Control System; T-S Model 目　　录 第一章　绪　　论 1 1.1模糊控制系统的产生与发展 1 1.1.1模糊控制理论的产生 1 1.1.2 模糊控制理论的发展概况 2 1.1.3 模糊控制的研究成果 2 1.1.4 有待解决的问题 4 1.2 本文的研究课题 4 1.2.1 选题意义 4 1.2.2 论文内容安排 5 1.3 本章小结 5 第二章 模糊控制理论基础 7 2.1 模糊数学基础 7 2.1.1 模糊集合 7 2.1.2 模糊运算 8 2.2 模糊逻辑与近似推理 10 2.3 模糊逻辑系统 11 2.4 T-S模糊系统 15 2.4.1 T-S模糊模型描述 15 2.4.2 T-S 模糊系统特点 16 2.5 本章小结 16 第三章 运用Matlab实现T-S模型模糊系统的设计 18 3.1 Matlab介绍 18 3.1.1 Matlab的优点 18 3.1.2 Matlab的缺点 19 3.2 模糊控制系统的设计 19 3.2.1 FIS编辑器 19 3.2.2 隶属度函数 22 3.2.3 根据模糊规则表编辑规则 25 3.2.4形成系统系统模型 26 第四章 仿真实例 28 第五章 结论和展望 32 5.1 主要结论 32 5.2 展望 32 参考文献 33 致　　谢 35 第一章　绪　　论 1.1模糊控制系
