AVEVA APC

AVEVA APC is comprehensive model predictive advanced process control software that improves process profitability by enhancing quality, increasing throughput, and reducing energy usage. It uses modern, state-of-the art technology to provide automatic control systems that are capable of releasing process potential across multiple industries including Refining, Petrochemical, Mining and Food and Beverage.

Data collection and analysis

AVEVA APC performs a series of process response tests, which collect dynamically-rich data with little or no disruption to normal process operations. Its statistical tools, including cross correlation and power spectrum density, allow an engineer to analyse signals for cause-and-effect interactions. These tools, coupled with operational experience, identify significant relationships that characterise process behaviour.

Multiple Model Sets and Gain Scheduling

A unique feature permits the application of model predictive control to processes that require multiple models. For example, in blending applications or seasonal production, AVEVA APC uses online gain scheduling and can switch automatically between multiple model sets without turning the controller off.

Control Systems Independence

AVEVA APC easily integrates with distributed control system (DCS), programmable logic controller (PLC) based control systems and plant information system databases from all major suppliers. AVEVA APC complies with the latest industry standards for data connectivity, such as OPC, which provides direct and efficient access to process data.

A Dynamic Model of the Process

AVEVA APC provides tighter control of key process variables, which are based on a dynamic model. This effectively de-couples interactions that would occur if the same loops were independently by single controllers. The result means a more economically advantageous operating point.

Linear programming

A linear programming technique, together with a steady-state model and an economic performance objective function enables AVEVA APC to identfy the optimum operating point based on maximum throughput, minimum energy consumption, or a balance between these and other performance objectives.
