Feedback linearizing indirect adaptive fuzzy control with foraging based on-line plant model estimation

The present paper describes the development of an indirect adaptive fuzzy control scheme employing feedback linearizing technique. The scheme proposes the development of a fuzzy certainty equivalence controller for controlling non-linear plants.
