Abstract :
This article aims to investigate the input-output parametric relationship of the crisp-type fuzzy logic controller (FLC) using the product-sum-gravity inference method, where the algebraic product, the summation, and the center-of-gravity method are selected to evaluate the final crisp output of the FLC. The explicit mathematical form of the reasoning surface is addressed and discussed. The local stability criteria for the PI-mode fuzzy control system is also investigated
