ABSTRACT:
The present invention relates systems and methods for compensating for errors associated with a linear motion system. The systems and methods determines one or more errors associated with the linear motion system and adjusts or corrects an input drive signal associated with the linear motion system to compensate for the one or more errors. The one or more errors of the linear motion system can include cogging errors and ripple errors. The one or more errors can be measured using a measurement system or the one or more errors can be associated with selectable coefficients or parameters, such as standard errors, or device type errors stored in a library.
