MFA vs Other Control
Methods Comparison
The following table provides a comparison of PID, Model
Predictive Control (MPC), Robust control design method,
Model-based Adaptive control, and Model-Free Adaptive
(MFA) control. It can be concluded that MFA combines the
merits of all of these control methods and is the best
candidate to be the next generation of mainstream process
controller.
