Description
Modern diffraction-limited storage ring light sources run at high beam currents and use harmonic cavities to lengthen the bunches for increased lifetime. These features make feedback control of the longitudinal coupled-bunch instabilities very challenging due to the bunches' wideband and variable dynamics. In the last few years, the long-ignored idea of using a differentiator as the feedback controller has made a comeback. I will outline the inherent control challenges, discuss the feedback controller design methodology, and present experimental results from several machines.
