An error value of +8mm can exist partially in For instance, say we have created a feedbackĬontroller that is based on the error of control.
)įuzzy Logic thus allows a degree of set membership. In the following picture, x is wholly in the sets A, B, and C in the traditionalĬan say x is in A to a degree of 0.7, 0.4 in B and 0.5 in C. Of a set or it isn’t, essentially a Boolean 1/0 classification. In traditional set theory, a variable is either an element Way they are helpful for problems that can not easily be set up mathematically, Fuzzy Logic Controllers are intended to “think” like humans do, in this
Logic was first developed in the state we know of now by Lofti Zadeh in the 1960’s. An Introduction to Fuzzy Logic Controllers in theįuzzy Logic is a variation on set theory where a variableĬan partially be an element of a set.
