Fuzzy Logic is used to implement a wide variety of intelligent control strategies. Fuzzy logic is a concept in which imprecise data can be processed precisely manner. There is variety of applications falling under three categories: Software Simulation, Software embedded in the Hardware and Total Hardware implementation. A simple application of Fuzzy Logic belonging to the second category is reported in the present paper. The hardware design based on 8-bit PIC microcontroller intends to control the AC voltage with FLC implemented through software. The fuzzy logically firing angle of thyrister is optimized to control the AC voltage. The Fuzzy Logical AC voltage control form the driving signal for physical parameter control such as temperature, pressure, speed of motor etc.
