Abstract:
Embodiments of the present invention provide improved accuracy of displacement control by using a multi-segment transformation of an actuator's non-linear response. The present invention may set intermediate points to effectively divide the actuator response into multiple segments. Each segment may be assigned a transform function that represents the actuator's response in that particular segment. The present invention may operate in two modes, a calibration mode and a normal operations mode. During calibration mode, the intermediate points and the segment transforms may be set. During normal operations mode, a drive signal may be generated according to the calibrated set values.
