FUZZY LOGIC AUGMENTED FEEDFORWARD - FEEDBACK CONTROL OF PROCESSES

摘要

This paper presents the Fuzzy Logic Augmented Feedforward-Feedback Control (FL FF-FBC)scheme to improve the performance of the original system (i.e. FF-FBC) by using a fuzzyprecompensator when a load disturbance occurs. From the computer simulation it is shown that thefuzzy logic augmented FF-FB Controller is robust in load disturbance rejection under the presence ofmodeling error and the approximation due to imperfect modeling thrust upon the implementation offeedforward controller (FFC).
