In its transformation to a hi-tech nation, China is using fuzzy logic to manufacture smart cars and consumer goods. In another application, an experiment with a train uses fuzzy logic to check power lines that keep trains running. With many specialists working in this field, China is well on its way to a fuzzy 21st century.
Fuzzy systems use a series of simple rules, based upon experience, much as the human brain does.
Fuzzy systems are also cheaper to produce. Fuzzy logic pioneer Lotfi Zadeh first labeled the concept in the 1960s, when he worked with fuzzy sets at the University of California at Berkeley. Japan embraced the concept of fuzzy logic and used the system to invent a myriad of smart machines. China soon followed and today has more fuzzy specialists than any other nation. The graph above illustrates the variable condition of a lamp controlled by a fuzzy logic circuit.
