A B S T R A C T SEISMIC VIBRATOR CONTROL An apparatus for the control of vibratory seismic source, said sources comprising at least a vibrator provided with a reaction mass and a coupling plate, the movement of which is responsive to an electrical input signal, the said plate being adapted to be brought into contact to the earth surface, comprising at least one means being adapted to measure the acceleration of the said plate and at least one means adapted to measure the acceleration of the reaction mass and means to derive corresponding force signals; at least a feedback loop for the said obtained force signals in order to be combined with the said input signal to the vibrator and the coupling plate. A method for controlling of vibratory seismic sources comprising a coupling plate, comprising the steps of generating electrical input signals to a vibrator; measuring at least the accelerations of the coupling plate and of the reaction mass and deriving corresponding force signals; combining the said force signals and feeding the combined signal through a feedback loop to the said input signal to the vibrator.
