Design of a dynamic fuzzy controller IC with application to garage parking control

Fuzzy controllers implemented in hardware can operate with much higher performance than software implementations on standard microcontrollers. In this paper, a dynamic fuzzy logic controller (FLC) and its hardware architectures are proposed. The FLC is realized on a CLPD chip. The presented circuits can dynamically generate fuzzy inference results when they are activated, so there is no need to design a large scale of ROM to store the fuzzy rules. Even we increase the resolutions of input and output variables and the universes of discourses, the increments of the gate counts are very few. Finally, a garage parking control system is used to demonstrate the effectiveness of the developed chip.
