On the hardware realization of general fuzzy controller

A new hardware realization methodology of fuzzy controller based on Multiple-Valued Logic (MVL) circuits is proposed. To the methodology, the hardware fuzzy inference process for different rule is executed in different time. The combination of the inference results of different rules makes fuzzy output, then it is changed to general output by defuzzification. According to this methodology, the complexity of the controller is free from the number of rules and the executive speed free from the dimension of fuzzy variables, furthermore, the choice of membership functions is free and the adjustment of fuzzy control rules is easy. The new methodology can be easily realized by using the very-large-scale-integration technique.
