    Abstract: In a stage assembly, for instance a fine stage using a pair of push-pull electro-magnetic actuators to move the stage back and forth along an axis, there is typically a sensor to determine the actual stage location. This sensor's home position must correspond to the actual stage position where the two opposed actuators are observed to exert forces of the same magnitude but opposing directions on this stage. Since the actuators depend on the sensor reading to exert their forces correctly, misalignment of the home position will decrease system performance. The calibration of this sensor is accomplished using actual system feedback signals, which are the currents drawn by the two opposed actuators, during run time conditions. The sensor is considered calibrated (meaning a virtual “null” position) when each of the two opposed actuators draws the same amount of current. If this is not the case a feedback process calibrates the sensor.

    Abstract: A pair of complementary magnetic actuators controls a stage in a high-precision positioning instrument in a single coordinate direction. Additional pairs of complementary magnetic actuators can be used to provide control of the stage in other coordinate directions. A small current through the windings of both magnetic actuators provides a zero net force on the fine stage, thus maintaining the position of the fine stage. The small current used to control the fine stage minimizes the RMS power gain. By increasing the current in one magnetic actuator while decreasing the current in the other, a net force is generated for large accelerations of the stage. Control of the magnetic actuators is simplified by simultaneously increasing and decreasing the current through the windings of the complementary magnetic actuators prior to accelerating the stage. Additionally, a feedforward command can control the magnetic actuators to decrease the settling time of the system.

    Abstract: Methods, apparatus, and systems are disclosed for identifying force-ripple and/or side-forces in actuators used for moving a multiple-axis stage. The identified force-ripple and/or side-forces can be mapped, and maps of corresponding position-dependent compensation ratios useful for correcting same are obtained. The methods are especially useful for stages providing motion in at least one degree of freedom using multiple (redundant) actuators. In an exemplary method a stage member is displaced, using at least one selected actuator, multiple times over a set distance in the range of motion of the subject actuator(s). Each displacement has a predetermined trajectory and respective starting point in the range. For each displacement, respective section force-command(s) are extracted and normalized to a reference section force-command to define a section compensation-ratio. Multiple section compensation-ratios are assembled, as functions of displacement in the range, to provide a map of compensation ratios for the actuator(s) throughout the range.
