Reevaluating “Advanced Control” in Industrial Applications: Beyond the PID Paradigm

PLC /

In academic circles, there is no specific algorithm formally defined as “advanced control.” Rather, the term broadly refers to any control strategy beyond the conventional PID (Proportional-Integral-Derivative) framework. In industrial practice, however, “advanced control” most commonly refers to Model Predictive Control (MPC). This article aims to revisit and clarify some common perceptions around advanced control
