When model-based multivariable control made its debut in the 1980s, it was expected that process models, once acquired through a plant step test, would be durable and long lived. However, this ...
Multivariable feedback control systems address the coordinated regulation of processes with multiple interacting inputs and outputs. By modelling the plant in state-space or frequency domains, ...
In this article, as in industry, advanced process control (APC) refers primarily to multi-variable control. Multivariable control means adjusting multiple single-loop controllers in unison, to meet ...
