Abstract
A seismic source signal apparatus for generating a seismic source signal may include a seismic source component for coupling a reaction mass to the earth; a controllable valve operatively connected to the seismic source component; and a controller controlling the controllable valve with a primary control signal generated by using a model of a response of the controllable valve over a selected operating range. The model is used to reduce nonlinearity in flow versus displacement response of the controllable valve.
