Abstract :
This paper compares algorithms used for control of super-conducting cavities in the FLASH accelerator and laser in DESY Research Center (Hamburg, Germany), and describes features of the adaptive feed-forward algorithm. Described solution was implemented in the PowerPC 405 processor embedded in the Xilinx Virtex II Pro FPGA circuit.
