In this paper, a kind of proportional expandable ＆ shrinkable factor is defined to replace conventional exponential factors and integral factors at the antecedent part and consequent part of inference. And a class of simple fuzzy control algorithm is presented based on variable universe of discourse. The existing algorithms＇ advantage of high precision is inherited by the controller consisted of the new algorithm. And comparing with existing algorithms, the new algorithm＇s computation is significantly reduced. So a useful way to problems in practical ap...
