      abstract     = {In the RF system for the Vacuum Ultraviolet Free Electron
                      Laser (VUV-FEL) Linac each klystron supplies RF power to up
                      to 32 cavities. The superconducting cavities are operated in
                      pulsed mode and high accelerating gradients close to the
                      performance limit. The RF control of the cavity fields to
                      the level of 10-4 foramplitude and 0.1 degree for phase
                      however presents a significant technical challenge due to
                      the narrow bandwidth of the cavities which results in high
                      sensitivity to perturbations of the resonance frequency by
                      mechanical vibrations (microphonics) and Lorenz force
                      detuning. The VUV-FEL Linac RF control system employs a
                      completely digital feedback system to provide flexibility in
                      the control algorithms, precise calibration of the
                      accelerating field vector-sum, and extensive diagnostics and
                      exception handling capabilities. The RF control algorithm is
                      implemented in DSP (Digital Signal Processor) firmware and
                      DOOCS (Distributed Object Oriented Control System) servers.
                      The RF control system design objectives are discussed.
                      Hardware and software design of the DSP based RF control are
