SNS Superconducting Cavity Modeling -Iterative Learning Control
Sung-il Kwon, Yi-Ming Wang, Amy Regan, Tony Rohlev, Mark Prokop, Dave Thomson
Abstract
The SNS SRF system is operated with a pulsed beam. For the SRF system to track the repetitive reference trajectory, a feedback and a feedforward controllers has been proposed. The feedback controller is to guarantee the closed loop system stability and the feedforward controller is to improve the tracking performance for the repetitive reference trajectory and to suppress the repetitive disturbance. As the iteration number increases, the error decreases.
