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

    Dynamically model your 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 controlled independently by single loop controllers. The result means a more economically-advantageous operating point.

    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.

    Optimize your process

    AVEVA™ APC manages process constraints such as absolute limits on valve motion and rate-of-change limits on process variables. AVEVA™ APC’s capability in this area includes the use of modern techniques such as quadratic programming.

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

    AVEVA™ APC easily integrates with DCS and PLC-based control systems and plant information system databases from all major suppliers. AVEVA™ APC is compliant with the latest industry standards for data connectivity, such as OPC, allowing direct and efficient access to process data.

    Optimize your process

    Process applications

    AVEVA™ APC can be used in any size process problem including those which exhibit significant time delays between the measured and controlled variables, interactions between process variables, or unmeasured variables which affect process operations.

    Industry expertise

    Significant cost and profit improvement from using AVEVA™ APC are proven in industries such as oil refining, petrochemical, food, metals and mining, power generation, and pulp and paper.
