Interference between the rules is an important index of the static features of a fuzzy controller. The traditional calculation of the interference density is based on fuzzy mathematics, which is not easy to put it into use because of its intricacy. The feasibility of calculating interference density by relative Euclidean distance is discussed with the help of tests in the article. The tests show that...
Some algorithms of close degree in fuzzy pattern recognition were researched and their limitations in application were found. So a new algorithm of close degree was proposed based on fluctuation thought in this paper. The whole relation between various elements and fuzzy set was considered in the new algorithm. It could avoid that the little change of membership grade in fuzzy set result in tremendous...
Because fuzzy control rules play an important part in determining the quality of a fuzzy controller, when the fuzzy control rules are extracted, the problem about how to get rid of the unreasonable or incompatible rules should be considered, when it is in the field where people is inexperienced. To better the quality of the fuzzy controller, a method of revising the rule which is incompatible with...
Phase plane analyzing approach is an intuitive graphical way for the analysis of fuzzy control system, and it can invert the movement of a first and second order system into the track of position and velocity in the phase plane, which is very important to further improve the whole system. However, it can't go without expertise and it is vague in the phase track drawing for stability determination...
