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.
