ABSTRACT:
An analog type fuzzy logic controller is adapted to permit the implementation of a set of rules. The controller includes a circuit (B,C) for determining the overall degree of truth of each rule and a circuit (D,E) for determining the values to be supplied at the output. The determination circuit of the overall degrees of truth of the various rules is composed of a network (C) of interconnected resistive elements. Each of the resistive elements is associated with a condition of a rule and is adapted to be commanded in such a way that its conductance is substantially proportional to the degree of truth of the associated condition. The current intensities circulating in the various branches (21,22,23) of the network are representative of the overall degrees of truth of the various rules.
