1. A controller, comprising:
one or more memory devices; and
one or more processors configured to execute an adaptive damping lag filter, and when the adaptive damping lag filter is executed, the one or more processors are configured to:
obtain a demanded position input of an actuating component for a current time step;
obtain a delta, wherein the delta is representative of a demanded position output of a prior time step subtracted from the demanded position input for the current time step;
determine a gain based at least in part on a size or a sign of the delta, wherein the gain is determined as one of a plurality of gains that include a slow gain, a fast tracking gain, and a fast recovery gain; and
output a demanded position output for the current time step based at least part on the gain.
