The project critically depends on the linear accelerator component, where radio frequency fields have to be controlled with a very high amplitude and phase precision and under various sources of disturbances. This paper shows for the first time closed loop results of dynamic fixed order H∞ controllers implemented in a FPGA based control system on the FLASH facility at DESY. ©2008 AACC.en0743-1619Proceedings of the American Control Conference200825162521IEEETechnikIngenieurwissenschaftenParameter estimation and tuning of a multivariable RF controller with FPGA technique for the Free Electron Laser FLASHConference Paper10.1109/ACC.2008.4586869Other
