The DeltaV Advanced Control manual contains information about DeltaV software advanced control capabilities. It includes detailed descriptions of the functions available with DeltaV InSight, DeltaV Fuzzy, DeltaV Simulate, and DeltaV Predict.
DeltaV InSight is used to examine the health of your control system, measurements, and actuators and to tune PID and Fuzzy Logic Control (FLC) function blocks. DeltaV InSight provides two selections: Inspect for performance monitoring and Tune for tuning.
Inspect for performance monitoring is used to analyze I/O function blocks (AI, AO, DI, DO, and PIN) and Control function blocks (DC, FLC, MPC, PID, and Ratio) for:
Tune automatically identifies models of processes controlled by PID and FLC function blocks during normal plant operations and automatically uses this information to provide tuning recommendations. Also, an option is provided to allow tuning to be established on demand based on automated plant testing using the relay self-oscillation principle. The tuning capabilities can be used to tune the control over a wide range of processes and addresses many of the requirements in a typical operating plant. This manual provides a description of how the process dynamics associated with a control loop are captured by DeltaV Tune. It also details how this information is used to tune your control loops.
DeltaV Fuzzy is an alternative to PID control that provides faster response and improved performance over standard PID control on most loops. The Fuzzy Logic Control (FLC) function block is the basis for DeltaV Fuzzy. This manual describes the FLC function block principles and its standard operations. It also provides references to other sections pertaining to this block.
DeltaV Simulate allows you to configure a DeltaV System on your laptop or office PC. You can configure all of the features that are supported by DeltaV software without having to use DeltaV hardware. Also, you can simulate the execution of the DeltaV Operate and control modules defined for your plant using a single workstation or distributed workstations without a physical controller. Using the Control and I/O block simulation capability of DeltaV software and fieldbus, you can either manually supply field measurement values and status or you can have them automatically provided by function blocks or applications that simulate the process.
DeltaV Predict implements model predictive control of small and medium-sized multivariable processes in DeltaV environments. You can control interactive processes within measurable operating constraints while automatically accounting for process interaction and measurable disturbances. DeltaV Predict also allows you to easily address the numerous small and medium-sized multivariable processes (2×2, 3×3 or 8×8) that can benefit from MPC technology.
DeltaV PredictPro implements model predictive control of large multivariable processes in DeltaV environments. It allows you to define as many as five control objectives for interactive processes within measurable operating constraints while automatically accounting for process interaction and measurable disturbances. With PredictPro you can easily address a wide variety of multivariable processes as large as 40×80 that can benefit from Model Predictive Control (MPC) technology.
DeltaV Neural is a collection of tools you use to implement neural networks in DeltaV environments. With DeltaV Neural you can create virtual sensors to monitor and predict process parameters that are otherwise expensive, difficult, or impossible to measure directly. Neural networks are sometimes referred to as intelligent or software sensors.
