<p>A high frequency injection system overlays a textured signal onto a digital control signal for controlling motion base. The system includes a digital motion controller (22) and HFIS generator (30) linked to a mixer (24). A mixed signal from the mixer (24) is amplified and provided to a valve (28) for controlling an actuator (18) for moving a motion base (10).</p> |
