中文摘要: 区间二型模糊系统具有优越的推理和处理不确定性的能力,它能广泛地应用到复杂不确定的实际系统中,如机器人、工业过程以及社会经济等领域。但区间二型模糊系统缺乏有效的系统分析和设计方法,在实际系统的稳定性与性能分析方面的理论方法还比较有限。针对复杂不确定非线性系统,根据T-S模型的建模方法,建立基于区间二型模糊控制系统模型。综合考虑区间二型T-S模糊系统的隶属度函数特征与信息,发展较为宽泛的稳定性分析以及控制器设计方法;在此基础上,进一步研究区间二型T-S模糊系统的输出反馈控制器以及多目标控制器设计等问题;在非线性不确定实际的工程系统背景下,提出有效的基于区间二型T-S模糊系统的控制设计方案;通过数值仿真与半实物仿真验证所提出控制方法的有效性。本项目的宗旨是提出一套较为完备的区间二型T-S模糊系统的建模、分析与控制综合方法,为实际工程系统的控制设计研究提供理论支持。

英文摘要: Interval type-2 fuzzy system (IT2FS) has demonstrated potential to handle ill-defined and complex applications with excellent performance because of its superior capability of reasoning and handling uncertainties. It is evident by a wide range of applications such as robots, industrial processes, socio-economic and so on. Lacking of systematic and effective analysis and design tools will hinder the application of IT2FS to real-world systems where the stability and performance are of important issues. For the complex uncertain nonlinear system, based on the T-S modeling method, this proposal investigates the problems of modeling, analysis and control synthesis for the IT2FS; By considering the property and the information of the membership function of the interval type-2 T-S fuzzy system (IT2TSFS), this project develops more relaxed stability analysis and controller design methods; Based on these approaches, this project further studies the output-feedback control and multi-objective control design problems; For the practical nonlinear uncertain system,based on IT2TSFS, the proposal develops an effective control design strategy; By utilizing numerical and semi-physical simulation, the effectiveness of the proposed control methods can be approved. The purpose of this project is to develop a more complete method f
