Method and apparatus for determining a valve transform
 The invention is an apparatus for determining a valve transform curve in a fluid system. The fluid system has a valve and a fluid actuator arranged to initiate movement of a load. The invention includes a desired velocity manager, a load responsive device, and a valve transform curve manager. The desired velocity manager determines a desired velocity of the load. The load responsive device determines a characteristic of the load, such as weight or position. The valve transform curve manager receives responsively determine a valve transform curve based on the desired velocity and load characteristic.
