Abstract

This paper presents a comprehensive three-stage computer-based methodology for the initial setting of the speed and torque controllers for the drives of a paper machine. First, the controller gains are selected based on the figures-of-merit for the frequency- and time-domain responses of each drive to commands and disturbances. After that, the effect of the elastic shafts is considered evaluating the resonant frequencies and two-mass system responses. Finally, the responses of each group of drives to the process commands and/or disturbances of interest are evaluated. The use of the proposed methodology will assure fast and well-behaved responses of each group of drives of the different sections of a paper machine, with minimal field adjustments. Index Terms--Controller setting, disturbance rejection, paper machine drive, speed and torque controllers, torsional oscillations.
