Abstract :
The paper consider a fuzzy inference scheme in the truth space that assumes the i-th rule linguistically qualified, that is, it comes with a truth value of the implication. In contrast to the standard version of modus ponens, the entire inference process is completed at the higher conceptual level formed by the mechanisms of fuzzy logic. The reasoning process invokes three phases: inverse linguistic truth qualification; inference based on fuzzy truth values exploiting the notion of fuzzy implication and the solution of an inverse relational equation; inverse linguistic truth qualification. An immediate application of the approach concerns fuzzy logic control
