How to achieve rapid positioning in the final stage of hydraulic servo?

The overshoot at the beginning of the move and undershoot at the end indicate that the Acceleration Feed Forward is too high. I also think you could use some Output Filter (larger value = less filtering) and then increase your proportional and integral gains as well.

For the Output Filter, I would start with a value like 50 Hz and reduce it if my control output was looking too “grassy” or fuzzy.
