A system for moving a load toward a setpoint includes an actuator connected to the load and a controller capable of controlling the operation of the actuator. The actuator can generate an input energy that is transferred to the load to move the load toward the setpoint, and the controller can control the operation of the actuator to move the load. The controller is also capable of determining a command distance based upon the setpoint and a current position of the load. Based upon the command distance, then, the controller can determine a pulse duration based upon the command distance. The controller can then apply an input pulse to the actuator for the pulse duration such that the actuator generates the input energy. Advantageously, the input pulse is applied such that the input energy equals an amount of energy lost by the load in moving the load toward the setpoint.
