Many motion applications require high accuracy both during, and at the end of, the move, but even if you are using perfectly optimized PID values to control position, the compensation loop is never perfect. You can improve motor performance by adding motion control elements outside of the PID loop. In this article, we will look at torque control and the related subject of torque FeedFoward, which will make your equipment run smoother, and deliver better accuracy.
