| Summary: | This paper describes the design and implementation of fast orbit feedback control in mode space. Using a Singular Value Decomposition (SVD) of the response matrix, each singular value can be associated with a spatial mode and enhanced feedback performance can be achieved by applying different controller dynamics to each spatial mode. By considering the disturbance spectrum across both dynamic and spatial frequencies, controller dynamics for each mode can be selected. Most orbit feedback systems apply only different gains to each mode however; mode space control gives greater flexibility in control design and can lead to enhanced disturbance suppression. Mode space control was implemented on the Booster synchrotron at Diamond Light Source, operated in stored beam mode. Implementation and performance of the mode space controller are presented. |
