DESIGN AND APPLICATION OF AN ANALOG FUZZY-LOGIC CONTROLLER

In this paper, we present an analog fuzzy logic hardware implementatio n and its application to an autonomous mobile system. With a simple st ructure the fabricated fuzzy controller shows good performance in proc essing speed and area consumption. Accomplished with 13 reconfigurable rules, a speed of up to 6 MFLIPS has been achieved. To stress the adv antages of the new architecture-speed and flexibility-the same control strategy is implemented on the new analog fuzzy controller and on a d igital multipurpose microcontroller in software. The results of the tw o implementations show-that the analog approach is not only faster but also enough flexible to compete digital fuzzy approaches.
