Elastic Adaptive Fuzzy Logic Controller

The authors present an adaptive fuzzy logic controller that includes on-line tuning of the membership function centroids and spreads, as well as an additional parameter, the “elasticity”. The notion of elasticity, taken from economics, allows weighting of the relative importance of each individual factor in a rule. A novel membership function is introduced here that satisfies certain important properties, including an independent reaction when the elasticity is tuned. We provide architecture for an elastic fuzzy logic adaptive controller, using certain on-line tuning laws that are an enhanced form of backpropagation tuning. It is shown by simulation that the fuzzy logic controller that includes the new membership function and tuning of elasticity outperforms the standard adaptive fuzzy logic controller based on Gaussian membership functions.
