Who Should Use Feed Forward Control? What applications are best for Feed Forward?

It’s not uncommon for process control discussions to focus on use of the PID to improve a loop’s ability to track Set Point. Oftentimes tweaks to controller tuning parameters either seek incremental reduction in Settling Time or strive to limit Overshoot. Indeed, many PID tuning courses position optimization of a control loop’s Set Point Tracking as the ultimate goal. Such a bias overlooks the value of other strategies like Feed Forward Control.
