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 ...

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 ...

The design of a range of challenging industrial control processes, carried out with the method of inequalities, is reviewed in this chapter. All the designs are in accordance with the conventional ...

APC Performance, LLC, recently briefed ARC Advisory Group on the company’s “next-generation” solution for advanced process control (APC). As we learned, this is designed to provide many of the ...

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, ...
