A study on maintaining control of tension for a catenary's cable

Abstract

This study shows the mathematical modeling of a catenary's system and tension generator; an AC servomotor. In the paper, the fuzzy control method is adopted that is robust because the model of a control object is nonlinear and time-variant system. Feedforward control is adopted to suppress overshoot as a shift begins to move. On the basis of the dynamic modeling of a catenary's cable we compose the control system adopting fuzzy and feedforward control and have recognized the effectiveness in a simulation experiment.
