Calculating the Tracking Filter Gains
The tracking filter gains are system dependent, and need to be fine-tuned. This can be done by gathering
and plotting filtered versus unfiltered data while moving the motor shaft manually. Best case scenario is
super-imposing the filtered data on top of the unfiltered with minimum ripple and overshoot.
The empirical equations for the filter’s proportional and integral gains (usually acceptable most
applications) present a good starting point:
