What does Dynamic Matrix Control combine to determine control actions?

• A. Operator knowledge and computer processing
• B. Random search with manual tuning
• C. Purely automatic optimization without operator input
• D. Mechanical feedback only

Answer: (A)

Dynamic Matrix Control relies on forecasting how the process will respond and using that forecast to choose the best actions. This approach blends the practical know-how of the operator with the power of automated computation. The operator provides essential insight—what limits matter, what the targets are, and what disturbances or safety constraints to expect—while the computer run the optimization to pick control moves that minimize a chosen cost over a future horizon. The result is actions that respect constraints and goals, guided by real process understanding, rather than blind trial-and-error or purely automatic steps without context. Other options don’t fit because they either rely on random, unfocused search, ignore real-world limits and objectives, or depend only on feedback without predictive optimization.
