　　Abstract: 

　　National Synchrotron Light Source II (NSLS-II) was completed in 2014, and has been in steady operation for users since early 2015. NSLS-II is a third generation 3GeV storage ring with 

　　ultra-low emittance. The low emittance requires a very stable electron beam orbit. The stringent orbit stability requires the orbit feedback system to be able to suppress various noises from low 

　　frequency ground motion to high frequency mechanical vibration. We designed and implemented the NSLS-II fast orbit feedback (FOFB) system with individual eigenmode compensation by taking advantage of the parallel computation capability of field programmable gate array(FPGA) chips.
