What is the core principle of feedforward control, and how is it applied in a hydrogen production plant?

The core principle of feedforward control is to anticipate the effect of disturbances on a process and take corrective action before the disturbance affects the process output. In other words, instead of waiting for an error to occur (as in feedback control), feedforward control measures the disturbance directly and adjusts the control variables to counteract its influence. In a hydrogen production....
