The fundamental difference between an interval type-2 (IT2) fuzzy controller and a type-1 is the footprint of uncertainty (FOU) IT2 set. In this paper, we study how FOUs affect analytical structure (i.e., input-output mathematical relationship) broad class Mamdani takagi-sugeno (TS) controllers. controllers employ arbitrary rules, Karnik-Mendel (KM) or Enhanced KM type-reducer, minimum AND operator, centroid defuzzifier. utilize commonly used sets for their input variables any kind output...
Existing topic tracking methods are mostly for news and forum data, which lack of statistical microblogging on relevant topics. Combined with characteristics micro-blog information, the paper proposes a based semantic similarity. Firstly by building model then use HowNet similarity calculation two terms, measures relevance microblogging. Finally statistics method is provided degree correlation. Experiments show that novel works problem soundly.
The fuzzy operator is one of the most important elements affecting control performance interval type-2 (IT2) proportional-integral (PI) controllers. At present, popular operators are product and min() operator. However, influence these two different types on IT2 PI controllers not clear. In this research, by studying derived analytical structure an controller using typical configurations, it proved mathematically that variable gains, i.e., proportional integral gains smaller than those...
Abstract Appropriate Footprint of Uncertainties (FOUs) are beneficial to the performance Interval Type-2 (IT2) fuzzy controller, revealing effect FOUs is a key problem. In our published work, as increase, IT2 Mamdani and TS controllers, using KM or EKM type-reducer (TR), approach constant piecewise linear respectively, while they finally become controllers. To verify validation above results, when different TR used, in this study, effects other popular TRs (i.e., Nie-Tan, Wu-Mendel,...
