摘要：

The high stability of electron energy required for FEL applications makes precise control of RF amplitude and phase necessary. An analog feedback loop is a possibility, but in a pulsed machine like ELSA [1], its transient response would last too long. For this reason, we developed an adaptive feedforward technique: the response of previous pulses is taken into account to correct the RF signal recurrently. The correction algorithm is given, the hardware is described and the performances are presented.
