Applying linear regression to speed control

Has anyone had any experience in applying a linear regression algorithm to their speed reference when communicating to a DC drive?

If so how is this best done?

Linear regression is not a means to make a non-linear function response more linear. Instead it is a means of finding a best-fit linear approximation to a given set of points.

If you want to make a non-linear response more linear, then there are several methods. One is to use a second or higher order polynomial to drive the motor speed command. Another is to break the range of commands up into segments and use a separate linear function in each segment.
