Kurzbeschreibung (Abstract)
A usual and effective way to realize closed-loop con- trollers is to use cascaded SISO feedback and to rely on some kind of linear PID (proportional, integral, derivative) structure often with parameters adjusted manually. Such a control may not reach optimal performance if the system is coupled or non-linear. Regarding intense beams, longitudi- nal beam loading can be compensated by detuning. But the coupling between phase and amplitude (or I and Q compo- nent) highly depends on the tuning, that is on the resonant frequency of the cavity. It is derived that cavity and beam dynamics show bi-linear nature, i.e. belong to a well inves- tigated class of non-linear systems with appropriate control strategies available [1, 4]. Different controller designs are compared. The perfor- mance evaluation is based on macro-particle tracking sim- ulations.
