Error propagation fuzzy control system

Abstract A concept of a fuzzy control system that adjusts itself upon the error propagation between the real system and the model is introduced. Different possible error outcomes are defined, namely, right (left) error, right (left) missed error, rule lost error, symmetry lost error, right (left) shift error, and nonresponsive error. An application to the truck backer-upper control problem is presented to corroborate the theory and demonstrate the utility of the approach to fuzzy control.
