Design of an analog adaptive fuzzy logic controller

An analog Adaptive fuzzy logic controller is proposed. This controller is based on back-propagation algorithm, and designed for the use of on chip learning. This adaptive fuzzy logic controller was composed of an analog fuzzy logic controller and a learning circuit that realizes online learning mechanism. It can tune the consequent parameters automatically with the help of a direction signal. Hspice simulation of functional approximation experiment was held, showing that this controller has the on-chip learning capability.
