ABSTRACT:
An architecture for an electronic controller operated using fuzzy logic, including an input section with a plurality of inputs for analog or digital signals, a central control unit provided with memories wherein fuzzy logic membership functions are stored) and a defuzzyfier section has its input section composed of a plurality of fuzzyfiers arranged in parallel and independent of one another, each fuzzyfier including an analog input and a digital input for receving signals from external sensors, and digital outputs connected to the input of a corresponding read-only memory of the central unit to select the address of a memory word.
Membership functions are stored and retrieved from a memory according to a method which simplifies addressing and reduces the number of required accesses.
