二型TSK模糊系统研究现状

Research status of type-2 TSK FLS

作为二型模糊系统的一个重要分支,二型TSK模糊系统在工程上的应用非常广泛,而国内在这一方面的研究还比较少.为此,综述了二型TSK模糊系统的研究现状.重点分析了一阶区间二型TSK模糊系统的3种结构及其推理过程,归纳了二型TSK模糊系统的适用范围,列举了近年来的一些成功应用案例,并通过一个短期电力负荷的预测实例验证了其在处理不确定方面的优越性.最后,总结了现阶段存在的不足,并指出了未来的发展方向,以期为以后的研究提供参考.

As an important branch of type-2 fuzzy logic system （FLS）,a type-2 Takagi-Sugeno-Kang （TSK）FLS has a very wide range of applications in engineering,and the domestic research in this sphere is still less.Therefore,the research status of type-2 TSK FLS was summarized.Three architectures of the first order interval type-2 TSK FLS and their inference procedures were mainly analyzed.Applicable ranges of type -2 TSK FLSs were concluded,some successful application cases in recent years were listed,and a simulation case of short-term power load forecast was presented to verify the superiority of type-2 TSK FLSs in dealing with uncertainties.Finally,the deficiency at present was summarized and the future development was pointed out in order to provide reference for the later research.
