Abstract

The implementation of improved technological process control systems (ITCS) represents one of the most effective ways to increase the efficiency of continuous industrial processes. This paper examines the interrelationship between virtual analyzers (VA) and advanced process control systems based on Model Predictive Control (MPC) technology.

An improved control system is presented as a multi-parameter control architecture for large technological objects that integrates MPC-controllers with a set of virtual analyzers. MPC-controllers enable proactive, multi-variable optimization by solving constrained optimization problems over a short-term prediction horizon using embedded dynamic models of the process. Virtual analyzers, in turn, provide real-time estimation of critical product quality indicators that are difficult or expensive to measure directly, using statistically or physically based models.
