Using Fuzzy Logic for Improving the Control Performance of Digital Servo Drives with Elastic Coupling

Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 267)

Abstract

In the paper a method for improving the control performance for a typical digital servo drive with a torsionable lead-screw and nonlinear static friction is presented. The method is based on employing an additional feedback the operational intensity of which is determined by means of fuzzy logic. Computer simulations show that the presented solution provides high control accuracy for motions at velocities close to zero and stepwise changes in the position set-point.
