New profits from advanced control

摘要

The big hits have already been madeinprocess control. This was said to me about three years ago by a technical director of a large North American paper company. "We're going to have to look elsewhere for our big profit and quality gains," he added. At the time, the paper industry's traditional feedback / feedforward computer controls seemed to be approaching a plateau in their effectiveness and return. Control improvements were evolutionary extensions of existing strategies rather than whole new concepts.
