Hydraulic servocylinder position control using a fuzzy logic controller

Abstract

A fuzzy logic controller, which consists of the linguistic defined fuzzy sets and the control rules, is designed and implemented in a microcomputer to control the position of an electrohydraulic servocylinder. Using the triangle shaped membership function, the normalized universe of discourse, and Tagagi and Sugeno's reasoning for the controller, the position of the servocylinder was successfully controlled.
