Changes in store for advanced process control
In advanced process control (APC), closed-loop multivariable control brings the inherent benefits of greater timeliness and consistency, fewer alarms and constraint violations and more effective process optimization. Multivariable control is core to most process operations. See “What is ‘real-time’ optimization?”

Artificial intelligence identifies process abnormality causes
When other methods fail, AI is a critical finding and solving tool
Feedforward: Not as popular as expected, again
Feedforward and feedback: Multivariable control, like single-loop control, can be accomplished primarily with feedback control and selective (not wholesale) use of feedforward.
Model-less multivariable control technology acquired
Lin and Associates, Inc. has agreed to acquire APC Performance LLC's model-less multivariable control (XMC) technology, which provides back-end control to distributed control systems and programmable controllers.
