In the process, batch and hybrid industries, deviations in product quality often take time to identify. The longer it takes to identify an off-spec product, the more costly the problem will be in time, raw materials, quality giveaway, waste and energy. It is critical to be able to accurately measure and control both process variables (pressure, level, flow, temperature, etc.) and product quality parameters. In cases where unmeasured disturbances are present, model predictive control techniques can be employed to manipulate the process conditions to maintain consistent product quality.
