Abstract
A fluid delivery system includes a pump operably coupleable to a source of fluid. A reciprocating electromagnetic actuator is coupled to the pump and has a coil that when energized causes the actuator to drive the pump. Coil current sensing circuitry is configured to provide an indication of current flowing in the coil. A controller is coupled to the coil current sensing circuitry and is configured to calculate a coil drive parameter based upon a plurality of coil current indications from the coil current sensing circuitry. Coil drive circuitry is coupled to the controller and is configured to supply current to the coil based on the coil drive parameter.
