This is caused solely because the PV is not taken into account in feedforward control, if it was it would become a feedback (closed loop) controlled system. Examination of the feedforward concept ...

These variances usually drive the process well outside its area of operation, and the feedback controller has little chance of making an accurate or rapid correction back to the SP term. The result of ...

Automatic control subsumes the ideas of feedback and feed-forward control; negative and positive feedback, and particularly requires that the "plant" being controlled exhibits some dynamics worth ...

Eventually, multivariable, model-predictive control replaced simpler APC approaches and algorithms for both feedforward and feedback control of complex process control applications. But, throughout ...

This article covers the in-code implementation of combined feedforward/PID control with WPILib's provided library classes. Documentation describing the involved concepts in more detail is forthcoming.
