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 ...

Five case studies show how diagnostic data used with multivariable process data increases process efficiency and uptime. Instrumentation selection for plant applications is a multistep process, ...

Technology progression within advanced process control (APC) continues to evolve; however, it is the relationship among core APC developments, enabling technologies, and management practices that is ...
