Understanding multivariable control: The missing metric

摘要

Multivariable control almost always has been explained in complex terms, invoking concepts such as detailed process models, real-time optimization, and matrix math. This means few people, outside the tight circle of advanced process control (APC) engineers, have understood it well. Greater understanding of multivariable control in industrial process operations brings more people into the process automation enterprise. Operational benefits include timeliness, consistency, and fewer alarms.
